TITLE: Linux Kernel Two Potential Denial of Service Vulnerabilities
SECUNIA ADVISORY ID: SA17114
VERIFY ADVISORY: http://secunia.com/advisories/17114/
CRITICAL: Not critical
WHERE: Local system
OPERATING SYSTEM: Linux Kernel 2.6.x http://secunia.com/product/2719/
DESCRIPTION: Two vulnerabilities have been reported in the Linux Kernel, which potentially can be exploited by malicious, local users to cause a DoS (Denial of Service).
1) A memory leak in "/security/keys/request_key_auth.c" can potentially be exploited by non-privileged users to cause a DoS.
2) A memory leak exists in "/fs/namei.c" when the CONFIG_AUDITSYSCALL option is enabled. This can potentially be exploited by local users to cause a DoS via an excessive number of system calls.
SOLUTION: The vulnerabilities have been fixed in version 2.6.14-rc4.
PROVIDED AND/OR DISCOVERED BY: 2) Robert Derr
