RHBA-2010:0016 - Bug Fix Advisory
Synopsis
glibc bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated glibc packages that fix a race condition while loading shared
libraries are now available
Description
The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contains the standard C and the
standard math libraries. Without these two libraries, the Linux system
cannot function properly.
These updated glibc packages provide a fix for the following bug:
- a rarely-encountered and difficult-to-reproduce race condition existed
between resolving dynamic symbols and loading shared libraries that could
have resulted in unresolved dependencies for a library. This update
provides a fix that avoids the potential race condition. (BZ#548690)
All users are advised to upgrade to these updated packages, which resolve
this issue.
