Description:
Secunia Research has discovered two vulnerabilities in WinRAR, which can be exploited by malicious people to compromise a user's system.
1) A format string error exists when displaying a diagnostic error message that informs the user of an invalid filename in an UUE/XXE encoded file. This can be exploited to execute arbitrary code when a malicious UUE/XXE file is decoded.
2) A boundary error in UNACEV2.DLL can be exploited to cause a stack-based buffer overflow. This allows arbitrary code execution when a malicious ACE archive containing a file with an overly long file name is extracted.
Vulnerability #2 is related to:
SA14359
The vulnerabilities have been confirmed in version 3.50. Prior versions may also be affected.
