SUSE SLES11 Security Update : kernel (SUSE-SU-2014:1698-1)

high Nessus Plugin ID 83653

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 Service Pack 2 LTSS kernel has been updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

CVE-2014-9322: A local privilege escalation in the x86_64 32bit compatibility signal handling was fixed, which could have been used by local attackers to crash the machine or execute code.

CVE-2014-9090: The do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel did not properly handle faults associated with the Stack Segment (SS) segment register, which allowed local users to cause a denial of service (panic) via a modify_ldt system call, as demonstrated by sigreturn_32 in the 1-clock-tests test suite.

CVE-2014-8133: Insufficient validation of TLS register usage could have leaked information from the kernel stack to userspace.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
