SuSE 11 Security Update : Linux kernel (SAT Patch Numbers 713 / 715 / 716)

medium Nessus Plugin ID 41410

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

This Linux kernel update for SUSE Linux Enterprise 11 fixes lots of bugs and some security issues.

The kernel was also updated to the 2.6.27.21 stable release.

- nfsd in the Linux kernel does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option. (CVE-2009-1072)

- The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request. The fix for this was incomplete. (CVE-2009-0676)

- The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod. (CVE-2009-0835)

Solution

Apply SAT patch number 713 / 715 / 716 as appropriate.
