TITLE:
Linux Kernel "do_coredump()" Information Disclosure

SECUNIA ADVISORY ID:
SA27908

VERIFY ADVISORY:
http://secunia.com/advisories/27908/

CRITICAL:
Not critical

IMPACT:
Exposure of sensitive information

WHERE:
Local system

OPERATING SYSTEM:
Linux Kernel 2.4.x
http://secunia.com/product/763/
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 disclose potentially sensitive
information.

The security issue is caused due to the "do_coredump()" function in
fs/exec.c not correctly verifying the user ID of a core dump file
when dumping the core into an existing file. This can be exploited to
e.g. gain access to sensitive information by tricking an application
with another user ID into dumping the core into a preexisting file.

The security issue is reported in 2.4.x and 2.6.x prior to
2.6.24-rc4.

SOLUTION:
Fixed in the stable prepatch version 2.6.24-rc4.

PROVIDED AND/OR DISCOVERED BY:
Reported in a bug by blake frantz.
