Debian Security Advisory DSA-1919-2 security@debian.org
http://www.debian.org/security/ Thijs Kinkhorst
August 17, 2010 http://www.debian.org/security/faq
- - ------------------------------------------------------------------------
Package : smarty
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2008-4810 CVE-2009-1669
Debian Bug : 504328 529810
A regression was found in the patch applied in DSA 1919-1 to smarty,
which caused compilation failures on some specific templates. This
update corrects the fix. For reference, the full advisory text below.
Several remote vulnerabilities have been discovered in Smarty, a PHP
templating engine. The Common Vulnerabilities and Exposures project
identifies the following problems:
CVE-2008-4810
The _expand_quoted_text function allows for certain restrictions in
templates, like function calling and PHP execution, to be bypassed.
CVE-2009-1669
The smarty_function_math function allows context-dependent attackers
to execute arbitrary commands via shell metacharacters in the equation
attribute of the math function.
For the stable distribution (lenny), this problem has been fixed in
version 2.6.20-1.3.
The testing (squeeze) and unstable distribution (sid) are not affected
by this regression.
We recommend that you upgrade your smarty package.
