Description

TITLE: Linux Kernel Two Potential Denial of Service Vulnerabilities

SECUNIA ADVISORY ID: SA17114

VERIFY ADVISORY: http://secunia.com/advisories/17114/

CRITICAL: Not critical

IMPACT: DoS

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
