Scientific Linux Security Update : glibc on SL5.x i386/x86_64 (20120827)

medium Nessus Plugin ID 61692
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

The glibc packages provide the standard C and standard math libraries used by multiple programs on the system. Without these libraries, the Linux system cannot function properly.

Multiple integer overflow flaws, leading to stack-based buffer overflows, were found in glibc's functions for converting a string to a numeric representation (strtod(), strtof(), and strtold()). If an application used such a function on attacker controlled input, it could cause the application to crash or, potentially, execute arbitrary code. (CVE-2012-3480)

This update also fixes the following bug :

- Previously, logic errors in various mathematical functions, including exp, exp2, expf, exp2f, pow, sin, tan, and rint, caused inconsistent results when the functions were used with the non-default rounding mode.
This could also cause applications to crash in some cases. With this update, the functions now give correct results across the four different rounding modes.

All users of glibc are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Solution

Update the affected packages.
