Description Tomas Hoger 2007-09-26 08:13:22 EDT

Common Vulnerabilities and Exposures assigned an identifier CVE-2007-3294 to the following vulnerability:

Multiple buffer overflows in libtidy, as used in the Tidy extension for PHP 5.2.3 and possibly other products, allow context-dependent attackers to execute arbitrary code via (1) a long second argument to the tidy_parse_string function or (2) an unspecified vector to the tidy_repair_string function.  NOTE: this might only be an issue in environments where vsnprintf is implemented as a wrapper for vsprintf.

Comment 1 Tomas Hoger 2007-09-26 08:19:17 EDT

This issue does not affect php as shipped in Red Hat Enterprise Linux 2.1, 3, 4,
or 5, as those packages are not built with libtidy support.

Comment 2 Tomas Hoger 2007-09-26 11:48:58 EDT

php-tidy in Fedora does not demonstrate any problems with large arguments passed
to tidy functions.
