Vulnerability Information

Synopsis

The remote openSUSE host is missing a security update.

Description

This update of glibc fixes various bugs and security issues :

CVE-2010-3847: Decoding of the $ORIGIN special value in various LD_ environment variables allowed local attackers to execute code in context of e.g. setuid root programs, elevating privileges. This issue does not affect SUSE as an assertion triggers before the respective code is executed. The bug was fixed nevertheless.

CVE-2010-3856: The LD_AUDIT environment was not pruned during setuid root execution and could load shared libraries from standard system library paths. This could be used by local attackers to inject code into setuid root programs and so elevated privileges.

CVE-2010-0830: Integer overflow causing arbitrary code execution in ld.so

--verify mode could be induced by a specially crafted binary.

CVE-2010-0296: The addmntent() function would not escape the newline character properly, allowing the user to insert arbitrary newlines to the /etc/mtab; if the addmntent() is run by a setuid mount binary that does not do extra input checking, this would allow custom entries to be inserted in /etc/mtab.

CVE-2008-1391: The strfmon() function contains an integer overflow vulnerability in width specifiers handling that could be triggered by an attacker that can control the format string passed to strfmon().

Solution

Update the affected glibc packages.

How to Run

Here is how to run the openSUSE Security Update : glibc (openSUSE-SU-2010:0913-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select SuSE Local Security Checks plugin family.
On the right side table select openSUSE Security Update : glibc (openSUSE-SU-2010:0913-1) plugin ID 50373.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl suse_11_2_glibc-101027.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_11_2_glibc-101027.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - suse_11_2_glibc-101027.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state suse_11_2_glibc-101027.nasl -t <IP/HOST>

Go back to menu.
