[DSA887] DSA-887-1 clamav

Vulnerability Assessment Summary
DSA-887-1 clamav

Detailed Explanation for this Vulnerability Assessment

Several vulnerabilities have been discovered in Clam AntiVirus, the
antivirus scanner for Unix, designed for integration with mail servers
to perform attachment scanning. The Common Vulnerabilities and
Exposures project identifies the following problems:
The OLE2 unpacker permits remote attackers to cause a segmentation
fault via a DOC file with an invalid property tree, which triggers
an infinite recursion.
A specially crafted executable compressed with FSG 1.33 could
cause the extractor to write beyond buffer boundaries, permiting an
attacker to execute arbitrary code.
A specially crafted CAB file could cause ClamAV to be locked in an
infinite loop and use all available processor resources, resulting
in a denial of service.
A specially crafted CAB file could cause ClamAV to be locked in an
infinite loop and use all available processor resources, resulting
in a denial of service.
The old stable distribution (woody) does not contain clamav packages.
For the stable distribution (sarge) these problems have been fixed in
version 0.84-2.sarge.6.
For the unstable distribution (sid) these problems have been fixed in
version 0.87.1-1.
We recommend that you upgrade your clamav packages.
