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 CAN-2004-0968 and CAN-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 CAN-2004-1453 to this issue.
This erratum also addresses the following bugs in the GNU C Library:
Users of glibc are advised to upgrade to these erratum packages that remove
the unecessary glibcbug script and contain backported patches to correct
these other issues.
