Scientific Linux Security Update : glibc on SL5.x i386/x86_64 (20131008)

medium Nessus Plugin ID 70393

Language:

Synopsis

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

Description

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in glibc's memory allocator functions (pvalloc, valloc, and memalign). If an application used such a function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2013-4332)

This update also fixes the following bug :

- Prior to this update, the size of the L3 cache in certain CPUs for SMP (Symmetric Multiprocessing) servers was not correctly detected. The incorrect cache size detection resulted in less than optimal performance for routines that used this information, including the memset() function. To fix this bug, the cache size detection has been corrected and core routines including memset() have their performance restored to expected levels.

Solution

Update the affected packages.
