Scientific Linux Security Update : glibc on SL5.x i386/x86_64 (20130424)

medium Nessus Plugin ID 66227
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.


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


It was found that getaddrinfo() did not limit the amount of stack memory used during name resolution. An attacker able to make an application resolve an attacker-controlled hostname or IP address could possibly cause the application to exhaust all stack memory and crash. (CVE-2013-1914)

A flaw was found in the regular expression matching routines that process multibyte character input. If an application utilized the glibc regular expression matching mechanism, an attacker could provide specially crafted input that, when processed, would cause the application to crash. (CVE-2013-0242)

This update also fixes the following bugs :

- The improvements made in a previous update to the accuracy of floating point functions in the math library caused performance regressions for those functions. The performance regressions were analyzed and a fix was applied that retains the current accuracy but reduces the performance penalty to acceptable levels.

- It was possible that a memory location freed by the localization code could be accessed immediately after, resulting in a crash. The fix ensures that the application does not crash by avoiding the invalid memory access.


Update the affected packages.
