GLSA-200704-21 : ClamAV: Multiple vulnerabilities
High Nessus Plugin ID 25109
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200704-21 (ClamAV: Multiple vulnerabilities)
iDefense Labs have reported a stack-based buffer overflow in the cab_unstore() function when processing negative values in .cab files.
Multiple file descriptor leaks have also been reported in chmunpack.c, pdf.c and dblock.c when processing .chm files.
A remote attacker could send a specially crafted CHM file to the scanner, possibly resulting in the remote execution of arbitrary code with the privileges of the user running ClamAV.
There is no known workaround at this time.
SolutionAll ClamAV users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-antivirus/clamav-0.90.2'
