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.
