GLSA-200511-04 : ClamAV: Multiple vulnerabilities
Critical Nessus Plugin ID 20154
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200511-04 (ClamAV: Multiple vulnerabilities)
ClamAV has multiple security flaws: a boundary check was performed incorrectly in petite.c, a buffer size calculation in unfsg_133 was incorrect in fsg.c, a possible infinite loop was fixed in tnef.c and a possible infinite loop in cabd_find was fixed in cabd.c . In addition to this, Marcin Owsiany reported that a corrupted DOC file causes a segmentation fault in ClamAV.
By sending a malicious attachment to a mail server that is hooked with ClamAV, a remote attacker could cause a Denial of Service or the execution of arbitrary code.
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-0.87.1'
