Summary
libxmltok vulnerability
Details

Tim Boddy discovered that Expat, contained within the xmltok library, did not properly handle memory reallocation when processing XML files. If a user or application linked against Expat were tricked into opening a crafted XML file, an attacker could cause a denial of service by consuming excessive memory resources.
