0.103.5 (2022-01-12) ClamAV 0.103.5 is a critical patch release with the following fixes: * CVE-2022-20698<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-20698>: Fix for invalid pointer read that may cause a crash. This issue affects 0.104.1, 0.103.4 and prior when ClamAV is compiled with libjson-c and the CL_SCAN_GENERAL_COLLECT_METADATA scan option (the clamscan --gen-json option) is enabled. Cisco would like to thank Laurent Delosieres of ManoMano for reporting this vulnerability. * Fixed ability to disable the file size limit with libclamav C API, like this: cl_engine_set_num(engine, CL_ENGINE_MAX_FILESIZE, 0); This issue didn't affect ClamD or ClamScan which also can disable the limit by setting it to zero using MaxFileSize 0 in clamd.conf for ClamD, or clamscan --max-filesize=0 for ClamScan. Note: Internally, the max file size is still set to 2 GiB. Disabling the limit for a scan will fall back on the internal 2 GiB limitation. * Increased the maximum line length for ClamAV config files from 512 bytes to 1,024 bytes to allow for longer config option strings. * SigTool: Fix insufficient buffer size for --list-sigs that caused a failure when listing a database containing one or more very long signatures. This fix was backported from 0.104. Special thanks to the following for code contributions and bug reports: * Laurent Delosieres |
