RHEL 5 : glibc (RHSA-2015:1627)

medium Nessus Plugin ID 85442

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated glibc packages that fix one security issue are now available for Red Hat Linux 5.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

An invalid free flaw was found in glibc's getaddrinfo() function when used with the AI_IDN flag. A remote attacker able to make an application call this function could use this flaw to execute arbitrary code with the permissions of the user running the application. Note that this flaw only affected applications using glibc compiled with libidn support. (CVE-2013-7424)

All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

Solution

Update the affected packages.
