Multiple vulnerabilities have been identified in Mozilla Firefox, SeaMonkey, and Thunderbird, which could be exploited by attackers to take complete control of an affected system or bypass security restrictions.
The first issue is due to a memory corruption error in the layout engine, which could be exploited by malicious people to cause a denial of service or execute arbitrary commands.
The second flaw is due to a memory corruption error in "XML.prototype.hasOwnProperty", which could be exploited by remote attackers to compromise a vulnerable system.
The third vulnerability is due to a memory corruption error in the JavaScript engine when processing malformed data, which could be exploited by attackers to crash a vulnerable application or execute arbitrary commands.
The fourth issue is due to an error when validating certain RSA digital signatures. This is a variant of FrSIRT/ADV-2006-3622
The fifth vulnerability is due to an error where certain Script objects could be modified during execution, which could be exploited by attackers to execute arbitrary JavaScript bytecode.
