Red Hat Security Advisory

Synopsis: Important: glibc security update
Advisory ID: RHSA-2010:0787-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0787.html
Issue date: 2010-10-20
CVE Names: CVE-2010-3847
================================================== ===================

1. Summary:

Updated glibc packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system cannot
function properly.

It was discovered that the glibc dynamic linker/loader did not handle the
$ORIGIN dynamic string token set in the LD_AUDIT environment variable
securely. A local attacker with write access to a file system containing
setuid or setgid binaries could use this flaw to escalate their privileges.
(CVE-2010-3847)

Red Hat would like to thank Tavis Ormandy for reporting this issue.

All users should upgrade to these updated packages, which contain a
backported patch to correct this issue.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

643306 - CVE-2010-3847 glibc: ld.so insecure handling of $ORIGIN in LD_AUDIT for setuid/setgid programs

1. Summary:

Updated glibc packages that fix one security issue are now available for
Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system cannot
function properly.

It was discovered that the glibc dynamic linker/loader did not perform
sufficient safety checks when loading dynamic shared objects (DSOs) to
provide callbacks for its auditing API during the execution of
privileged programs. A local attacker could use this flaw to escalate
their privileges via a carefully-chosen system DSO library containing
unsafe constructors. (CVE-2010-3856)

Red Hat would like to thank Ben Hawkes and Tavis Ormandy for reporting this
issue.

All users should upgrade to these updated packages, which contain a
backported patch to correct this issue.

relevant to your system have been applied.

================================================== ===================

1. Summary:

Updated glibc packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system cannot
function properly.

The fix for CVE-2010-3847 introduced a regression in the way the dynamic
loader expanded the $ORIGIN dynamic string token specified in the RPATH and
RUNPATH entries in the ELF library header. A local attacker could use this
flaw to escalate their privileges via a setuid or setgid program using
such a library. (CVE-2011-0536)

It was discovered that the glibc addmntent() function did not sanitize its
input properly. A local attacker could possibly use this flaw to inject
malformed lines into /etc/mtab via certain setuid mount helpers, if the
attacker were allowed to mount to an arbitrary directory under their
control. (CVE-2010-0296)

It was discovered that the glibc fnmatch() function did not properly
restrict the use of alloca(). If the function was called on sufficiently
large inputs, it could cause an application using fnmatch() to crash or,
possibly, execute arbitrary code with the privileges of the application.
(CVE-2011-1071)

It was discovered that the locale command did not produce properly escaped
output as required by the POSIX specification. If an attacker were able to
set the locale environment variables in the environment of a script that
performed shell evaluation on the output of the locale command, and that
script were run with different privileges than the attacker's, it could
execute arbitrary code with the privileges of the script. (CVE-2011-1095)

All users should upgrade to these updated packages, which contain
backported patches to correct these issues.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at

3. Description:

The glibc packages contain the standard C libraries used by multiple
programs on the system. These packages contain the standard C and the
standard math libraries. Without these two libraries, a Linux system cannot
function properly.

The fix for CVE-2010-3847 introduced a regression in the way the dynamic
loader expanded the $ORIGIN dynamic string token specified in the RPATH and
RUNPATH entries in the ELF library header. A local attacker could use this
flaw to escalate their privileges via a setuid or setgid program using
such a library. (CVE-2011-0536)

It was discovered that the glibc fnmatch() function did not properly
restrict the use of alloca(). If the function was called on sufficiently
large inputs, it could cause an application using fnmatch() to crash or,
possibly, execute arbitrary code with the privileges of the application.
(CVE-2011-1071)

It was discovered that the locale command did not produce properly escaped
output as required by the POSIX specification. If an attacker were able to
set the locale environment variables in the environment of a script that
performed shell evaluation on the output of the locale command, and that
script were run with different privileges than the attacker's, it could
execute arbitrary code with the privileges of the script. (CVE-2011-1095)

All users should upgrade to these updated packages, which contain
backported patches to correct these issues.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
