Summary
======
A vulnerability and a security issue have been fixed, which can be
exploited by malicious, local users to bypass certain security
restrictions, cause a DoS (Denial of Service), and potentially gain
escalated privileges.
Description
==========
CVE-2010-0622:
The wake_futex_pi function in kernel/futex.c in the Linux kernel does
not properly handle certain unlock operations for a Priority Inheritance
(PI) futex, which allows local users to cause a denial of service (OOPS)
and possibly have unspecified other impact via vectors involving
modification of the futex value from user space.
CVE-2010-0623:
The futex_lock_pi function in kernel/futex.c in the Linux kernel does
not properly manage a certain reference count, which allows local users
to cause a denial of service (OOPS) via vectors involving an unmount of
an ext3 filesystem.
Affected packages:
Pardus 2008:
kernel, all before 2.6.25.20-114-58
Resolution
=========
There are update(s) for kernel. You can update them via Package Manager
or with a single command from console:
pisi up kernel
