Description

Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. A flaw was found in expat. The vulnerability occurs due to large content in element type declarations when there is an element declaration handler present which leads to an integer overflow. This flaw allows an attacker to inject an unsigned integer, leading to a crash or a denial of service.
