ClamAV 1.0.2

ClamAV 1.0.2 is a critical patch release with the following fixes:

CVE-2023-20197
Fixed a possible denial of service vulnerability in the HFS+ file parser.
This issue affects versions 1.1.0, 1.0.1 through 1.0.0, 0.105.2 through 0.105.0,
0.104.4 through 0.104.0, and 0.103.8 through 0.103.0.
Thank you to Steve Smith for reporting this issue.
CVE-2023-20212
Fixed a possible denial of service vulnerability in the AutoIt file parser.
This issue affects versions 1.0.1 and 1.0.0.
This issue does not affect version 1.1.0.
Fixed a build issue when using the Rust nightly toolchain, which was
affecting the oss-fuzz build environment used for regression tests.
- GitHub pull request: #996
Fixed a build issue on Windows when using Rust version 1.70 or newer.
- GitHub pull request: #993
CMake build system improvement to support compiling with OpenSSL 3.x on
macOS with the Xcode toolchain.

The official ClamAV installers and packages are now built with OpenSSL 3.1.1
or newer.
- GitHub pull request: #973
Fixed an issue where ClamAV does not abort the signature load process after
partially loading an invalid signature.
The bug would later cause a crash when scanning certain files.
- GitHub pull request: #952
Fixed an issue so that ClamAV correctly removes temporary files generated
by the VBA and XLM extraction modules so that the files are not leaked in
patched versions of ClamAV where temporary files are written directly to the
temp-directory instead of writing to a unique subdirectory.
- GitHub pull request: #900
Set Git attributes to prevent Git from altering line endings for bundled Rust
libraries. Third-party Rust libraries are bundled in the ClamAV release
tarball. We do not commit them to our own Git repository, but community
package maintainers may now store the tarball contents in Git.
The Rust build system verifies the library manifest, and this change
ensures that the hashes are correct.
Improvement courtesy of Nicolas R.
- GitHub pull request: #856
Fixed two bugs that would cause Freshclam to fail update when applying a
CDIFF database patch if that patch adds a file to the database archive
or removes a file from the database archive.
This bug also caused Sigtool to fail to create such a patch.
- GitHub pull request: #901

clamav-1.2.0-rc

78ad993

ClamAV 1.2.0-rc Pre-release

Pre-release

1.2.0

ClamAV 1.2.0 includes the following improvements and changes:

Major changes

Added support for extracting Universal Disk Format (UDF) partitions.

Specifically, this version adds support for the Beginning Extended Area
Descriptor (BEA01) type of UDF files.
- GitHub pull request: #941
Added an option to customize the size of ClamAV's clean file cache.

Increasing the size of the clean file cache may improve scan performance
but will require more RAM. The cache size value should be a square number
or will be rounded up to the nearest square number.

The cache size option for clamd and clamscan is --cache-size.
Alternatively, you can customize the cache size for ClamD by setting
CacheSize in clamd.conf.

Patch courtesy of Craig Andrews.
- GitHub pull request: #882
Introduced a SystemD timer for running Freshclam updates, without sending
Freshclam into the background. This takes the "burden of timing the updates"
from Freshclam and puts it onto SystemD.
The timer can be activated, audited, and the logs inspected:
```
sudo systemctl enable --now clamav-freshclam-once.timer
sudo systemctl list-timers
sudo systemctl status clamav-freshclam-once.timer
sudo systemctl status clamav-freshclam-once.service
journalctl -u clamav-freshclam-once.service
```
If you want a different update interval you can edit the timer unit file:
```
sudo systemctl edit clamav-freshclam-once.timer
```
Patch courtesy of Nils Werner.
- GitHub pull request: #962
Raised the MaxScanSize limit so the total amount of data scanned when
scanning a file or archive may exceed 4 gigabytes.

Introduced the ability to suffix the MaxScanSize and other config file size
options with a "G" or "g" for the number of gigabytes.
For example, for ClamD you may now specify MaxScanSize 10G in clamd.conf.
And for ClamScan, you may now specify --max-scansize=10g.

The MaxFileSize is still limited internally in ClamAV to 2 gigabytes.
Any file, or embedded file, larger than 2GB will be skipped.
You may use clamscan --alert-exceeds-max, or the clamd.conf option
AlertExceedsMax yes to tell if a scan is not completed because of
the scan limits.

Patch courtesy of matthias-fratz-bsz.
- GitHub pull request: #945
Added ability for Freshclam to use a client certificate PEM file and a
private key PEM file for authentication to a private mirror by setting the
following environment variables:
- FRESHCLAM_CLIENT_CERT: May be set to the path of a file (PEM) containing
  the client certificate.
- FRESHCLAM_CLIENT_KEY: May be set to the path of a file (PEM) containing
  the client private key.
- FRESHCLAM_CLIENT_KEY_PASSWD: May be set to a password for the client key
  PEM file, if it is password protected.
Patch courtesy of jedrzej.
- GitHub pull request: #955

Other improvements

Fix an issue extracting files from ISO9660 partitions where the files are
listed in the plain ISO tree and there also exists an empty Joliet tree.
- GitHub pull request: #938
CMake build system improvement to support compiling with OpenSSL 3.x on
macOS with the Xcode toolchain.

The official ClamAV installers and packages are now built with OpenSSL 3.1.1
or newer.
- GitHub pull request: #970
The suggested path for the clamd.pid and clamd.sock file in the sample
configs have been updated to reflect the recommended locations for these files
in the Docker images. These are:
- /run/clamav/clamd.pid
- /run/clamav/clamd.sock
For consistency, it now specifies clamd.sock instead of clamd.socket.

Patch courtesy of computersalat.
- GitHub pull request: #931

Bug fixes

Fixed an issue where ClamAV does not abort the signature load process after
partially loading an invalid signature. The bug would later cause a crash when
scanning certain files.
- GitHub pull request: #934
Fixed a possible buffer over-read bug when unpacking PE files.
- GitHub pull request: #927
Removed a warning message showing the HTTP response codes during the
Freshclam database update process.
- GitHub pull request: #935
Added missing command line options to the ClamD and ClamAV-Milter --help
message and manpages.
- GitHub pull request: #936
ClamOnAcc: Fix error message when using --wait without --ping option.
Patch courtesy of Răzvan Cojocaru.
- GitHub pull request: #984

clamav-1.1.0

2a21451

ClamAV 1.1.0

ClamAV 1.1.0 includes the following improvements and changes:

Major changes

Added the ability to extract images embedded in HTML CSS <style> blocks.
- GitHub pull request: #813
Updated to Sigtool so that the --vba option will extract VBA code from
Microsoft Office documents the same way that libclamav extracts VBA.
This resolves several issues where Sigtool could not extract VBA.
Sigtool will also now display the normalized VBA code instead of the
pre-normalized VBA code.
- GitHub pull request: #852
Added a new ClamScan and ClamD option: --fail-if-cvd-older-than=days.
Additionally, we introduce FailIfCvdOlderThan as a clamd.conf synonym for
--fail-if-cvd-older-than. When passed, it causes ClamD to exit on startup
with a non-zero return code if the virus database is older than the specified
number of days.
- GitHub pull request: #867
Added a new function cl_cvdgetage() to the libclamav API.
This function will retrieve the age in seconds of the youngest file in a
database directory, or the age of a single CVD (or CLD) file.
- GitHub pull request: #867
Added a new function cl_engine_set_clcb_vba() to the libclamav API.
Use this function to set a cb_vba callback function.
The cb_vba callback function will be run whenever VBA is extracted from
office documents. The provided data will be a normalized copy of the
extracted VBA.
This callback was added to support Sigtool so that it can use the same VBA
extraction logic that ClamAV uses to scan documents.
- GitHub pull request: #852

Other improvements

Removed the vendored TomsFastMath library in favor of using OpenSSL to
perform "big number"/multiprecision math operations.
Work courtesy of Sebastian Andrzej Siewior.
- GitHub pull request: #840
Build system: Added CMake option DO_NOT_SET_RPATH to avoid setting
RPATH on Unix systems.
Feature courtesy of Sebastian Andrzej Siewior.
- GitHub pull request: #815
Build system: Enabled version-scripts with CMake to limit symbol exports for
libclamav, libfreshclam, libclamunrar_iface, and libclamunrar shared
libraries on Unix systems, excluding macOS.
Improvement courtesy of Orion Poplawski and Sebastian Andrzej Siewior.
- GitHub pull request: #776
Build system: Enabled users to pass in custom Rust compiler flags using the
RUSTFLAGS CMake variable.
Feature courtesy of Orion Poplawski.
- GitHub pull request: #835
Removed a hard-coded alert for CVE-2004-0597.
The CVE is old enough that it is no longer a threat and the detection had
occasional false-positives.
- GitHub pull request: #855
Set Git attributes to prevent Git from altering line endings for Rust
vendored libraries. Third-party Rust libraries are bundled in the ClamAV
release tarball. We do not commit them to our own Git repository, but
community package maintainers may now store the tarball contents in Git.

ensures that the hashes are correct.
Improvement courtesy of Nicolas R.
- GitHub pull request: #800
Fixed compile time warnings.
Improvement courtesy of Răzvan Cojocaru.
- GitHub pull request: #795
Added a minor optimization when matching domain name regex signatures for
PDB, WDB and CDB type signatures.
- GitHub pull request: #837
Build system: Enabled the ability to select a specific Python version.
When building, you may use the CMake option -D PYTHON_FIND_VER=<version>
to choose a specific Python version.
Feature courtesy of Matt Jolly.
- GitHub pull request: #787
Added improvements to the ClamOnAcc process log output so that it is
easier to diagnose bugs.
- GitHub pull request: #822
Windows: Enabled the MSI installer to upgrade between feature versions more
easily when ClamAV is installed to a location different from the default
(i.e., not C:\Program Files\ClamAV). This means that the MSI installer can
find a previous ClamAV 1.0.x installation to upgrade to ClamAV 1.1.0.
- GitHub pull request: #872
Sigtool: Added the ability to change the location of the temp directory
using the --tempdir option and added the ability to retain the temp files
created by Sigtool using the --leave-temps option.
- GitHub pull request: #852
Other minor improvements.

Bug fixes

Fixed the broken ExcludePUA / --exclude-pua feature.
Fix courtesy of Ged Haywood and Shawn Iverson.
- GitHub pull request: #780
Fixed an issue with integer endianness when parsing Windows executables on
big-endian systems.
Fix courtesy of Sebastian Andrzej Siewior.

This issue is not a vulnerability.
- GitHub pull request: #807
Fixed a possible index out of bounds when loading CRB signatures.
This issue is not a vulnerability.
- GitHub pull request: #810
Fixed a possible use after free when reading logical signatures.
This issue is not a vulnerability.

Fixed a possible heap overflow read in javascript normalizer module.
This issue is not a vulnerability.
- GitHub pull request: #868

Fixed an assortment of complaints identified by Coverity static analysis.
- GitHub pull requests:
  - #891
  - #899
Fixed one of the Freshclam tests that was failing on some Fedora systems
due to a bug printing debug-level log messages to stdout.
Fix courtesy of Arjen de Korte.
- GitHub pull request: #881
Correctly remove temporary files generated by the VBA and XLM extraction
modules so that the files are not leaked in patched versions of ClamAV
where temporary files are written directly to the temp-directory instead
of writing to a unique subdirectory.
