RHBA-2009:1634 - glibc bug fix update

Synopsis

glibc bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated glibc packages that resolve several issues 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 fixes for the following bugs:

  • when a thread calls the setuid() function, the change of credentials needs to be performed in every thread as per POSIX requirements. This update corrects the implementation to avoid a race condition which occurred when a thread terminated or a new thread was created while the credential change was performed. (BZ#533213)

  • the implementation of the seg_timedwait() function, in assembler, incorrectly decremented the number of waiting threads stored in a block of memory when an invalid nanosecond value was passed through its second argument. This error is corrected in this update. (BZ#540475)

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

Solution

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