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.

    • 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

  • 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.

    • 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.

    • 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.

    • 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.
