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 old stable distribution (etch), these problems have been fixed in version 2.6.14-1etch2. For the stable distribution (lenny), these problems have been fixed in version 2.6.20-1.2. For the unstable distribution (sid), these problems will be fixed soon. We recommend that you upgrade your smarty package.
