RHBA-2012:1422 - 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, an error in memory management within the glibc nscd daemon resulted in attempts to free a pointer that was not provided by the malloc() function. Consequently, nscd could terminate unexpectedly. This bug only happened when handling groups with a large number of members. This update ensures that memory allocated by the pool allocator is no longer passed to "free". Instead, we allow the pool allocator's garbage collector to reclaim the memory. As a result, nscd no longer crashes on groups with a large number of members. (BZ#864046)

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

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
