Summary: CA Anti-Virus engine contains multiple vulnerabilities that can allow a remote attacker to cause a denial of service or possibly execute arbitrary code. CA has issued an update to address the vulnerabilities. The first vulnerability, CVE-2007-2863, is due to insufficient bounds checking on filenames contained in a CAB archive. The second vulnerability, CVE-2007-2863, is due to insufficient bounds checking on the "coffFiles" field. By using a specially malformed CAB file, an attacker can cause a crash or take unauthorized action on an affected system.
