| Description: | A denial of service vulnerability has been found in libhtml-parser-perl, a collection of modules to parse HTML in text documents which is used by several other projects like e.g. SpamAssassin. Mark Martinec discovered that the decode_entities function will get stuck in an infinite loop when parsing certain HTML entities with invalid UTF-8 characters. An attacker can use this to perform denial of service attacks by submitting crafted HTML to an application using this functionality. For the oldstable distribution, this problem has been fixed in version 3.55-1+etch1. For the stable distribution, this problem has been fixed in version 3.56-1+lenny1. For the testing and unstable distribution, this problem will be fixed soon. We recommend that you upgrade your libhtml-parser-perl packages. |
