Discussion

Mozilla Suite/Firefox JavaScript Lambda Replace Heap Memory Disclosure Vulnerability

Mozilla Suite/Firefox are reported prone to a memory-disclosure vulnerability. This issue can allow a remote attacker to access arbitrary heap memory.

Due to an error in the way 'replace()' handles lambda expressions, a remote attacker can access arbitrary heap memory from a vulnerable client.

Information harvested in this manner could then aid in further attacks launched against the vulnerable computer (such as memory-corruption exploits).

Firefox versions 1.0.1 and 1.0.2 are reported vulnerable. Mozilla 1.7.6 is vulnerable as well. Other versions may also be affected.

K-Meleon 0.9 is vulnerable to this issue. Older versions may be affected as well.

Camino 0.8.3 is affected by this issue. Other versions of Camino may be affected as well.
