(CVE-2014-1574)

Atte Kettunen discovered a buffer overflow during CSS manipulation. If a user were tricked in to opening a specially crafted message, 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-2014-1576)

Holger Fuhrmannek discovered an out-of-bounds read with Web Audio. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to steal sensitive information. (CVE-2014-1577)

Abhishek Arya discovered an out-of-bounds write when buffering WebM video in some circumstances. If a user were tricked in to opening a specially crafted message with scripting enabled, 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-2014-1578)

A use-after-free was discovered during text layout in some circumstances. If a user were tricked in to opening a specially crafted message with scripting enabled, 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.

Eric Shepherd and Jan-Ivar Bruaroey discovered issues with video sharing via WebRTC in iframes, where video continues to be shared after being stopped and navigating to a new site doesn’t turn off the camera.
