Mandriva Linux Security Advisory : kernel (MDVSA-2010:088)
Medium Nessus Plugin ID 48181
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel :
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. (CVE-2009-3620)
fs/namei.c in Linux kernel 2.6.18 through 2.6.34 does not always follow NFS automount symlinks, which allows attackers to have an unknown impact, related to LOOKUP_FOLLOW. (CVE-2010-1088)
The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 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-2010-0622)
drivers/connector/connector.c in the Linux kernel before 126.96.36.199 allows local users to cause a denial of service (memory consumption and system crash) by sending the kernel many NETLINK_CONNECTOR messages. (CVE-2010-0410)
The futex_lock_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 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. (CVE-2010-0623)
Aditionally, the kernel was updated to the 188.8.131.52 stable release, it was added support for Cirrus Logic CS420x HDA codec, Wacom driver was updated to version 0.8.5-12 and there is a fix in the driver for backlight on Eee PC 1201HA.
