RHBA-2012:1158 - glibc bug fix update

Synopsis

glibc bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated glibc packages that fix one bug are now available for Red Hat Enterprise Linux 6.

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 correctly.

This update fixes the following bug:

• Prior to this update, glibc incorrectly handled the "options rotate" option in the /etc/resolv.conf file when this file also contained one or more IPv6 name servers. Consequently, DNS queries could unexpectedly fail, particularly when multiple queries were issued by a single process. This update fixes internalization of the listed servers from /etc/resolv.conf into glibc's internal structures, as well as the sorting and rotation of those structures to implement the "options rotate" capability. Now, DNS names are resolved correctly in glibc in the described scenario. (BZ#843571)

Users of glibc are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
