Red Hat has released a glibc update for Red Hat Enterprise Linux
[RHSA-2012:1097-01] Moderate: glibc security and bug fix update
=====================================================================
Red Hat Security Advisory
Synopsis: Moderate: glibc security and bug fix update
Advisory ID: RHSA-2012:1097-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1097.html
Issue date: 2012-07-18
CVE Names: CVE-2012-3406
=====================================================================
1. Summary:
Updated glibc packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having moderate
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 provide the standard C and standard math libraries used
by multiple programs on the system. Without these libraries, the Linux
system cannot function properly.
It was discovered that the formatted printing functionality in glibc did
not properly restrict the use of alloca(). This could allow an attacker to
bypass FORTIFY_SOURCE protections and execute arbitrary code using a format
string flaw in an application, even though these protections are expected
to limit the impact of such flaws to an application abort. (CVE-2012-3406)
This update also fixes the following bug:
* If a file or a string was in the IBM-930 encoding, and contained the
invalid multibyte character "0xffff", attempting to use iconv() (or the
iconv command) to convert that file or string to another encoding, such as
UTF-8, resulted in a segmentation fault. With this update, the conversion
code for the IBM-930 encoding recognizes this invalid character and calls
an error handler, rather than causing a segmentation fault. (BZ#837896)
All users of glibc are advised to upgrade to these updated packages, which
contain backported patches to fix 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/knowledge/articles/11258
5. Bugs fixed (http://bugzilla.redhat.com/):
826943 - CVE-2012-3406 glibc: printf() unbound alloca() usage in case of positional parameters + many format specs

3. Description:
The glibc packages provide the standard C and standard math libraries used
by multiple programs on the system. Without these libraries, the Linux
system cannot function properly.
Multiple errors in glibc's formatted printing functionality could allow an
attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code
using a format string flaw in an application, even though these protections
are expected to limit the impact of such flaws to an application abort.
(CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)
This update also fixes the following bug:
* A programming error caused an internal array of nameservers to be only
partially initialized when the /etc/resolv.conf file contained IPv6
nameservers. Depending on the contents of a nearby structure, this could
cause certain applications to terminate unexpectedly with a segmentation
fault. The programming error has been fixed, which restores proper behavior
with IPv6 nameservers listed in the /etc/resolv.conf file. (BZ#837026)
All users of glibc are advised to upgrade to these updated packages, which
contain backported patches to fix 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

5. Bugs fixed (http://bugzilla.redhat.com/):
826943 - CVE-2012-3406 glibc: printf() unbound alloca() usage in case of positional parameters + many format specs
833703 - CVE-2012-3404 glibc: incorrect size calculation in formatted printing can lead to FORTIFY_SOURCE format string protection bypass
833704 - CVE-2012-3405 glibc: incorrect use of extend_alloca() in formatted printing can lead to FORTIFY_SOURCE format string protection bypass
837026 - libresolv dumps core when IPv6 address in resolv.conf

Red Hat Security Advisory
Synopsis: Moderate: glibc security and bug fix update
Advisory ID: RHSA-2012:1097-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-1097.html
Issue date: 2012-07-18
CVE Names: CVE-2012-3406
=====================================================================
1. Summary:
Updated glibc packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having moderate
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 provide the standard C and standard math libraries used
by multiple programs on the system. Without these libraries, the Linux
system cannot function properly.
It was discovered that the formatted printing functionality in glibc did
not properly restrict the use of alloca(). This could allow an attacker to
bypass FORTIFY_SOURCE protections and execute arbitrary code using a format
string flaw in an application, even though these protections are expected
to limit the impact of such flaws to an application abort. (CVE-2012-3406)
This update also fixes the following bug:
* If a file or a string was in the IBM-930 encoding, and contained the
invalid multibyte character "0xffff", attempting to use iconv() (or the
iconv command) to convert that file or string to another encoding, such as
UTF-8, resulted in a segmentation fault. With this update, the conversion
code for the IBM-930 encoding recognizes this invalid character and calls
an error handler, rather than causing a segmentation fault. (BZ#837896)
All users of glibc are advised to upgrade to these updated packages, which
contain backported patches to fix 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/knowledge/articles/11258
5. Bugs fixed (http://bugzilla.redhat.com/):
826943 - CVE-2012-3406 glibc: printf() unbound alloca() usage in case of positional parameters + many format specs

3. Description:
The glibc packages provide the standard C and standard math libraries used
by multiple programs on the system. Without these libraries, the Linux
system cannot function properly.
Multiple errors in glibc's formatted printing functionality could allow an
attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code
using a format string flaw in an application, even though these protections
are expected to limit the impact of such flaws to an application abort.
(CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)
This update also fixes the following bug:
* A programming error caused an internal array of nameservers to be only
partially initialized when the /etc/resolv.conf file contained IPv6
nameservers. Depending on the contents of a nearby structure, this could
cause certain applications to terminate unexpectedly with a segmentation
fault. The programming error has been fixed, which restores proper behavior
with IPv6 nameservers listed in the /etc/resolv.conf file. (BZ#837026)
All users of glibc are advised to upgrade to these updated packages, which
contain backported patches to fix these issues.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

833703 - CVE-2012-3404 glibc: incorrect size calculation in formatted printing can lead to FORTIFY_SOURCE format string protection bypass
833704 - CVE-2012-3405 glibc: incorrect use of extend_alloca() in formatted printing can lead to FORTIFY_SOURCE format string protection bypass
