Detail

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.

Id Description
20536 Clam AntiVirus OLE2 Unpacker ole2_walk_property_tree Function DoS

Clam AntiVirus contains a flaw that may allow a remote denial of service. The problem ist that the 'ole2_walk_property_tree()' function in the OLE2 unpacker does not properly handle malformed OLE2 files. With a malformed .doc file containing an invalid property tree, a remote attacker can cause the application to enter an infinite loop resulting in a loss of availability.
20484 Clam AntiVirus libclamav/mspack/cabd.c Infinite Loop DoS

Clam AntiVirus contains a flaw that may allow a remote denial of service. The issue is triggered due to a design error of the 'cabd_find()' function in 'libclamv/mspack/cabd.c'. With a specially crafted CAB file, a remote attacker can cause the application to enter an infinite loop and consume all available CPU resources resulting in a loss of availability.
20483 Clam AntiVirus tnef.c tnef_attachment Function Infinite Loop DoS

Clam AntiVirus contains a flaw that may allow a remote denial of service. The issue is triggered due to a design error of the 'tnef_attachment()' function in 'tnef.c', which uses an user controlled value of the 'fseek()' function to move the file pointer to a specific byte in a file. With a specially crafted CAB file, a remote attacker can cause the application to enter an infinite loop resulting in a loss of availability.
20482 Clam AntiVirus libclamav/fsg.c FSG File Processing Overflow

A remote overflow exists in Clam AntiVirus. The 'unfsg_133()' function in 'libclamav/fsg.c' fails to perform proper bounds checking resulting in a heap-based buffer overflow. With a specially crafted file compressed with FSG v1.33, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
