This signature detects attempts to exploit a known vulnerability against Colloquy Internet Chat client. A successful attack can lead to arbitrary code execution.
Colloquy is prone to a remote format-string vulnerability because the application fails to properly sanitize user-supplied input before including it in the format-specifier argument of a formatted-printing function. Successfully exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the application and to compromise affected computers. A denial-of-service condition may arise as well. Colloquy versions prior to 2.1 (3558) are vulnerable; other versions may also be affected.
