"Updated glibc packages that address several bugs are now available.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

The GNU libc packages (known as glibc) contain the standard C
libraries used by applications.

Flaws in the catchsegv and glibcbug scripts were discovered. A local
user could utilize these flaws to overwrite files via a symlink attack
on temporary files. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0968 and CVE-2004-1382
to these issues.

It was discovered that the use of LD_DEBUG and LD_SHOW_AUXV were not
restricted for a setuid program. A local user could utilize this flaw
to gain information, such as the list of symbols used by the program.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-1453 to this issue.

This erratum also addresses the following bugs in the GNU C Library: -
Now avoids calling sigaction (SIGPIPE, ...) in syslog implementation -
Fixed poll on Itanium - Now allows setenv/putenv in shared library
constructors

Users of glibc are advised to upgrade to these erratum packages that
remove the unnecessary glibcbug script and contain backported patches
to correct these other issues."
