Title : Clam AntiVirus File Handling Denial of Service Vulnerabilities VUPEN ID : VUPEN/ADV-2005-0922 CVE ID : CVE-2005-1922 - CVE-2005-1923 CWE ID : CWE-
Rated as : Low Risk
Remotely Exploitable : Yes Locally Exploitable : Yes Release Date : 2005-06-30
Technical Description
Two vulnerabilities were identified in Clam AntiVirus (ClamAV), which could be exploited by attackers to cause a denial of service.
- The first issue exists due to insufficient validation on cabinet file header data performed by the "ENSURE_BITS()" macro, which could be exploited via a specially crafted cabinet file to cause an infinite loop.
- The second flaw resides in the "cli_msexpand()" function that causes two file descriptors ("in" and "tmp") to be leaked, which could be exploited by attackers to exhaust file descriptors pool and memory.
