Two vulnerabilities in ClamAV may allow for the remote execution of arbitrary code or a Denial of Service.
|Package||app-antivirus/clamav on all architectures|
|Affected versions||< 0.94.2|
|Unaffected versions||>= 0.94.2|
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.
Moritz Jodeit reported an off-by-one error within the get_unicode_name() function in libclamav/vba_extract.c when processing VBA project files (CVE-2008-5050). Ilja van Sprundel reported an infinite recursion error within the cli_check_jpeg_exploit() function in libclamav/special.c when processing JPEG files (CVE-2008-5314).
A remote attacker could send a specially crafted VBA or JPEG file to the clamd daemon, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application or a Denial of Service.
There is no known workaround at this time.
All ClamAV users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.94.2"
