TITLE: ncpfs "ncpmount" / "ncpumount" Race Condition Security Issues SECUNIA ADVISORY ID: SA38327 VERIFY ADVISORY: http://secunia.com/advisories/38327/ DESCRIPTION: Some security issues have been reported in ncpfs, which can be exploited by malicious, local users to disclose potentially sensitive information, cause a DoS (Denial of Service), and potentially gain escalated privileges. The security issues are caused due to unspecified race conditions within the "ncpmount" and "ncpumount" utilities, which can be exploited via symlink attacks. Note: Successful exploitation may require that the affected utilities are suid root. SOLUTION: Restrict access to trusted users only.
