Smarty before 3.0.0 beta 7 does not properly handle the <?php and ?> tags, which has unspecified impact and remote attack vectors.

Unspecified vulnerability in Smarty before 3.0.0 beta 6 allows remote attackers to execute arbitrary PHP code by injecting this code into a cache file.

The _expand_quoted_text function in libs/Smarty_Compiler.class.php in Smarty 2.6.20 r2797 and earlier allows remote attackers to execute arbitrary PHP code via vectors related to templates and a \ (backslash) before a dollar-sign character.

The _expand_quoted_text function in libs/Smarty_Compiler.class.php in Smarty 2.6.20 before r2797 allows remote attackers to execute arbitrary PHP code via vectors related to templates and (1) a dollar-sign character, aka "php executed in templates;" and (2) a double quoted literal string, aka a "function injection security hole." NOTE: each vector affects slightly different SVN revisions.

PHP remote file inclusion vulnerability in unit_test/test_cases.php in Smarty 2.6.1 allows remote attackers to execute arbitrary PHP code via a URL in the SMARTY_DIR parameter. NOTE: this issue is disputed by CVE and a third party because SMARTY_DIR is a constant
