Synopsis: Moderate: glibc security and bug fix update

Advisory ID: RHSA-2012:0125-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0125.html

Issue date: 2012-02-13

CVE Names: CVE-2009-5029 CVE-2009-5064 CVE-2010-0296

CVE-2010-0830 CVE-2011-1071 CVE-2011-1089

CVE-2011-1095 CVE-2011-1659 CVE-2011-4609

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

 

1. Summary:

 

Updated glibc packages that fix multiple security issues and one bug are

now available for Red Hat Enterprise Linux 4.

 

The Red Hat Security Response Team has rated this update as having moderate

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 AS version 4 - i386, ia64, ppc, s390, s390x, x86_64

Red Hat Enterprise Linux Desktop version 4 - i386, x86_64

Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64

Red Hat Enterprise Linux WS version 4 - i386, ia64, 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.

 

An integer overflow flaw, leading to a heap-based buffer overflow, was

found in the way the glibc library read timezone files. If a

carefully-crafted timezone file was loaded by an application linked against

glibc, it could cause the application to crash or, potentially, execute

arbitrary code with the privileges of the user running the application.

(CVE-2009-5029)

 

A flaw was found in the way the ldd utility identified dynamically linked

libraries. If an attacker could trick a user into running ldd on a

malicious binary, it could result in arbitrary code execution with the

privileges of the user running ldd. (CVE-2009-5064)

 

It was discovered that the glibc addmntent() function, used by various

mount helper utilities, did not sanitize its input properly. A local

attacker could possibly use this flaw to inject malformed lines into the

mtab (mounted file systems table) file via certain setuid mount helpers, if

the attacker were allowed to mount to an arbitrary directory under their

control. (CVE-2010-0296)

 

An integer overflow flaw, leading to a heap-based buffer overflow, was

found in the way the glibc library loaded ELF (Executable and Linking

Format) files. If a carefully-crafted ELF file was loaded by an

application linked against glibc, it could cause the application to crash

or, potentially, execute arbitrary code with the privileges of the user

running the application. (CVE-2010-0830)

 

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 found that the glibc addmntent() function, used by various mount

helper utilities, did not handle certain errors correctly when up[censored] the

mtab (mounted file systems table) file. If such utilities had the setuid

bit set, a local attacker could use this flaw to corrupt the mtab file.

(CVE-2011-1089)

 

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)

 

An integer overflow flaw was found in the glibc fnmatch() function. If an

attacker supplied a long UTF-8 string to an application linked against

glibc, it could cause the application to crash. (CVE-2011-1659)

 

A denial of service flaw was found in the remote procedure call (RPC)

implementation in glibc. A remote attacker able to open a large number of

connections to an RPC service that is using the RPC implementation from

glibc, could use this flaw to make that service use an excessive amount of

CPU time. (CVE-2011-4609)

 

Red Hat would like to thank the Ubuntu Security Team for reporting

CVE-2010-0830, and Dan Rosenberg for reporting CVE-2011-1089. The Ubuntu

Security Team acknowledges Dan Rosenberg as the original reporter of

CVE-2010-0830.

 

This update also fixes the following bug:

 

* When using an nscd package that is a different version than the glibc

package, the nscd service could fail to start. This update makes the nscd

package require a specific glibc version to prevent this problem.

(BZ#657009)

 

Users should upgrade to these updated packages, which resolve 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
