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: CVE-2005-3239 The OLE2 unpacker allows remote attackers to cause a segmentation fault via a DOC file with an invalid property tree, which triggers an infinite recursion. CVE-2005-3303 A specially crafted executable compressed with FSG 1.33 could cause the extractor to write beyond buffer boundaries, allowing an attacker to execute arbitrary code. CVE-2005-3500 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. CVE-2005-3501 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.
