openSUSE Security Update : kernel (openSUSE-SU-2013:1042-1)

High Nessus Plugin ID 75048

Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE 12.2 kernel was updated to fix security issue and other bugs.

Security issues fixed: CVE-2013-2850: Incorrect strncpy usage in the network listening part of the iscsi target driver could have been used by remote attackers to crash the kernel or execute code.

This required the iscsi target running on the machine and the attacker able to make a network connection to it (aka not filtered by firewalls).

CVE-2013-2094: The perf_swevent_init function in kernel/events/core.c in the Linux kernel used an incorrect integer data type, which allowed local users to gain privileges via a crafted perf_event_open system call.

CVE-2013-0290: The __skb_recv_datagram function in net/core/datagram.c in the Linux kernel did not properly handle the MSG_PEEK flag with zero-length data, which allowed local users to cause a denial of service (infinite loop and system hang) via a crafted application.

Bugs fixed :

- reiserfs: fix spurious multiple-fill in reiserfs_readdir_dentry (bnc#822722).

- reiserfs: fix problems with chowning setuid file w/ xattrs (bnc#790920).

- qlge: fix dma map leak when the last chunk is not allocated (bnc#819519).

- Update config files: disable UCB1400 on all but ARM Currently UCB1400 is only used on ARM OMAP systems, and part of the code is dead code that can't even be modularized.

- CONFIG_UCB1400_CORE=n

- CONFIG_TOUCHSCREEN_UCB1400=n

- CONFIG_GPIO_UCB1400=n

- mm/mmap: check for RLIMIT_AS before unmapping (bnc#818327).

- unix/stream: fix peeking with an offset larger than data in queue (bnc#803931 CVE-2013-0290).

- unix/dgram: fix peeking with an offset larger than data in queue (bnc#803931 CVE-2013-0290).

- unix/dgram: peek beyond 0-sized skbs (bnc#803931 CVE-2013-0290).

Solution

Update the affected kernel packages.
