openSUSE Security Update : glibc (openSUSE-SU-2010:0913-1)

This script is Copyright (C) 2010-2014 Tenable Network Security, Inc.


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().
