Several bugs were discovered in Clam AntiVirus, the antivirus scanner for Unix, designed for integration with mail servers to perform attachment scanning. The following problems were identified :

  • CAN-2005-2450 Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is vulnerable to integer overflows when handling the TNEF, CHM and FSG file formats.

  • CVE-NOMATCH

    Mark Pizzolato fixed a possible infinite loop that could cause a denial of service.
