RHEL 3 : glibc (RHSA-2005:256)

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


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.

It was discovered that the use of LD_DEBUG, LD_SHOW_AUXV, and
LD_DYNAMIC_WEAK 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 addresses the following bugs in the GNU C Library :

- fix stack alignment in IA-32 clone - fix double free in
globfree - fix fnmatch to avoid jumping based on
unitialized memory read - fix fseekpos after ungetc -
fix TZ env var handling if the variable ends with + or -
- avoid depending on values read from unitialized memory
in strtold on certain architectures - fix mapping
alignment computation in dl-load - fix i486+ strncat
inline assembly - make gethostid/sethostid work on
bi-arch platforms - fix ppc64 getcontext/swapcontext -
fix pthread_exit if called after pthread_create, but
before the created thread actually started - fix return
values for tgamma (+-0) - fix handling of very long
lines in /etc/hosts - avoid page aliasing of thread
stacks on AMD64 - avoid busy loop in malloc if
concurrent with fork - allow putenv and setenv in shared
library constructors - fix restoring of CCR in
swapcontext and getcontext on ppc64 - avoid using
sigaction (SIGPIPE, ...) in syslog implementation

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