Releases

• Ubuntu 16.04 ESM
• Ubuntu 15.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• expat - XML parsing C library

Details

Gustavo Grieco discovered that Expat incorrectly handled malformed XML
data. If a user or application linked against Expat were tricked into
opening a crafted XML file, an attacker could cause a denial of service, or
possibly execute arbitrary code. (CVE-2016-0718)
