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
