RHEL 2.1 : glibc (RHSA-2005:261)

low Nessus Plugin ID 18160

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
