______________________________________________________________________________
An update that solves 5 vulnerabilities and has 26 fixes is
now available. It includes one version update.
Description:
The SUSE Linux Enterprise 11 SP2 kernel was updated to
3.0.34, fixing a lot of bugs and security issues.
The update from Linux kernel 3.0.31 to 3.0.34 also fixes
various bugs not listed here.
The following security issues have been fixed:
*
CVE-2012-2136: Local attackers could trigger an
overflow in sock_alloc_send_pksb(), potentially crashing
the machine or escalate privileges.
*
CVE-2012-2390: A memory leak in transparent hugepages
on mmap failure could be used by local attacker to run the
machine out of memory (local denial of service).
*
CVE-2012-2119: A malicious guest driver could
overflow the host stack by passing a long descriptor, so
potentially crashing the host system or escalating
privileges on the host.
*
CVE-2012-2375: Malicious NFS server could crash the
clients when more than 2 GETATTR bitmap words are returned
in response to the FATTR4_ACL attribute requests, only
incompletely fixed by CVE-2011-4131.
