X11: X Font Server Character Swap
This signature detects attempts to exploit a known vulnerability against Solaris XFS. A successful attack can lead to arbitrary code execution.
Extended Description
X.Org X Font Server (XFS) is prone to multiple memory-corruption vulnerabilities, including an integer-overflow issue and a heap-based memory-corruption issue. An attacker could exploit this issue to execute arbitrary code with the privileges of the X Font Server. Failed exploit attempts will likely result in a denial-of-service condition. NOTE: These issues are exploitable remotely only on Solaris operating systems; by default the server is listening on TCP port 7100. For other UNIX-like operating systems, an attacker can exploit these issues only locally. These issues affect X Font Server 1.0.4; prior versions may also be affected.
