Description
Apache HTTP Server contains a flaw that may allow a remote attacker to gain privileges. The issue is due to the mod_ssl extension module not properly validating Certificate Revocation Lists (CRL). By sending a crafted CRL, an attacker can exploit an off-by-one error in mod_ssl to cause a buffer overflow. This may allow the attacker to crash the web server or potentially execute arbitrary code.
