APP: CVS Directory Heap Overflow
This signature detects attempts to exploit a known vulnerability against the double free () function in Concurrent Versions System protocol. Attackers sending an over long directory name can cause a heap double free on some CVS systems.
Extended Description
CVS is prone to a double free vulnerability in the Directory requests. An attacker may potentially take advantage of this issue to cause heap memory to be corrupted with attacker-supplied values, which may result in execution of arbitrary code.
