[GLSA-200511-04] ClamAV: Multiple vulnerabilities

Vulnerability Assessment Summary
ClamAV: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The 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.

Impact

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.

Workaround

There is no known workaround at this time.
