Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3157-1 - Donncha O Cearbhaill discovered that the crash file parser in Apport improperly treated the CrashDB field as python code. An attacker could use this to convince a user to open a maliciously crafted crash file and execute arbitrary code with the privileges of that user. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Donncha O Cearbhaill discovered that Apport did not properly sanitize the Package and SourcePackage fields in crash files before processing package specific hooks. An attacker could use this to convince a user to open a maliciously crafted crash file and execute arbitrary code with the privileges of that user. Various other issues were also addressed.
