Details

Ben Turner, Bobby Holley, Jesse Ruderman and Christian Holler 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. (CVE-2013-5609)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in event listeners. If a user had enabled scripting, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-5616)

A use-after-free was discovered in the table editing interface. An attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-5618)

Tyson Smith and Jesse Schwartzentruber discovered a crash when inserting an ordered list in to a document using script. If a user had enabled scripting, an attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-6671)

Sijie Xia discovered that trust settings for built-in EV root certificates were ignored under certain circumstances, removing the ability for a user to manually untrust certificates from specific authorities. (CVE-2013-6673)

Tyson Smith, Jesse Schwartzentruber and Atte Kettunen discovered a use-after-free in functions for synthetic mouse movement handling. If a user had enabled scripting, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2013-5613)

Eric Faust discovered that GetElementIC typed array stubs can be generated outside observed typesets. If a user had enabled scripting, an attacker could possibly exploit this to cause undefined behaviour with a potential security impact. (CVE-2013-5615)

Michal Zalewski discovered several issues with JPEG image handling. An attacker could potentially exploit these to obtain sensitive information. (CVE-2013-6629, CVE-2013-6630)
