This signature detects attempts to exploit a known vulnerability in Mozilla Network Security Services. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the client.
Mozilla Firefox and Seamonkey are prone to a heap-based buffer-overflow vulnerability in the regular expression parser used to match common names in SSL certificates. Successfully exploiting this issue can allow attackers to execute arbitrary code in the context of the application. Failed attempts will likely cause denial-of-service conditions. Note that attackers need to exploit this issue with a crafted certificate that SeaMonkey trusts; otherwise, a warning message will be presented to the user. SeaMonkey 1.09 and Firefox 3.0.x are vulnerable; other versions may also be affected. This issue is related to the vulnerability described by BID 35888 (Mozilla Firefox NULL Character CA SSL Certificate Validation Security Bypass Vulnerability).
