Debian DSA-1923-1 : libhtml-parser-perl - denial of service

medium Nessus Plugin ID 44788

Language:

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the libhtml-parser-perl packages.

For the oldstable distribution (etch), this problem has been fixed in version 3.55-1+etch1.

For the stable distribution (lenny), this problem has been fixed in version 3.56-1+lenny1.
