RHBA-2010:0562 - Bug Fix Advisory

Topic

Updated glibc packages that fix various bugs are now available.

Description

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

This update fixes the following bugs:

• under certain circumstances, unloading a module could leave the remaining

modules' symbol search list in an inconsistent state. Consequent to this
inconsistency, symbol lookups could spuriously fail to find the symbol. This
update corrects this: module unloading no longer produces inconsistent state in
the symbol search list. (BZ#604193)

• previously, there was an error in the POWER6 implementation of the "memcpy"

and "memset" functions. As a result, using Concurrent Versions System (CVS) with
Kerberos authentication on the 32-bit PowerPC architecture may have failed with
a segmentation fault. This error has been fixed, and both "memcpy" and "memset"
functions now work as expected. (BZ#614546)

All users are advised to upgrade to these updated packages, which resolve these
issues.

Solution

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