SECUNIA ADVISORY ID:
SA28070

VERIFY ADVISORY:
http://secunia.com/advisories/28070/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
Local system

OPERATING SYSTEM:
Linux Kernel 2.6.x
http://secunia.com/product/2719/

DESCRIPTION:
A security issue has been reported in the Linux Kernel, which can be
exploited by malicious, local users to bypass certain security
restrictions.

The security issue is caused due to the improper enforcing of the
"mmap_min_addr" limit. This can be exploited to allocate pages lower
than "mmap_min_addr" by expanding the stack or via "do_brk()" in
specially crafted binaries.

The security issue affects all 2.6.23 versions.

SOLUTION:
Fixed in version 2.6.24-rc5.

PROVIDED AND/OR DISCOVERED BY:
