Ubuntu Security Notice 2119-1 - Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen and Sotaro Ikeda discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Cody Crews discovered a method to bypass System Only Wrappers. If a user had enabled scripting, an attacker could potentially exploit this to steal confidential data or execute code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
