Scientific Linux Security Update : xen on SL5.x i386/x86_64

medium Nessus Plugin ID 61034

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

It was found that the xc_try_bzip2_decode() and xc_try_lzma_decode() decode routines did not correctly check for a possible buffer size overflow in the decoding loop. As well, several integer overflow flaws and missing error/range checking were found that could lead to an infinite loop. A privileged guest user could use these flaws to crash the guest or, possibly, execute arbitrary code in the privileged management domain (Dom0). (CVE-2011-1583)

The system must be rebooted for this update to take effect.

Solution

Update the affected packages.
