|Gentoo Linux Security Advisory
Title: ClamAV: Multiple vulnerabilities (GLSA 200812-21)
Date: December 23, 2008
Bug(s): #245450, #249833
Two vulnerabilities in ClamAV may allow for the remote execution of arbitrary code or a Denial of Service.
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.
Vulnerable: < 0.94.2
Unaffected: >= 0.94.2
Architectures: All supported architectures
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"
