RHBA-2014:1213 - glibc bug fix update

Synopsis

glibc bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated glibc packages that fix several bugs are now available for Red Hat Enterprise Linux 5.

Description

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.

This update fixes the following bugs:

  • An attempt to start an already running service by using the "service" command should result in a zero exit code. However, due to an error in the nscd init script, the "service nscd start" command returned a non-zero exit code. This update corrects the nscd init script and this command returns a zero exit code as expected in the described situation. (BZ#979413)

  • The getgroups() function incorrectly accepted a negative size value and then terminated unexpectedly if a related program was compiled with optimizations enabled and the FORTIFY_SOURCE parameter was set to 2. This update corrects the getgroups() function to return an EINVAL error in such cases. (BZ#995207)

  • The size of the L3 cache in certain CPUs for SMP (Symmetric Multiprocessing) servers was not correctly detected. The incorrect cache size detection resulted in less than optimal performance for routines that used this information, including the memset() function. To fix this problem, the cache size detection has been corrected and core routines including memset() work with the expected efficiency. (BZ#1003420)

  • The getnameinfo() function previously failed on a reverse lookup of an IP address that had a large number of PTR records associated with it. This problem has been corrected and getnameinfo() now correctly returns one of the PTR records as the response. (BZ#1020486)

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.
