Security researcher Khalil Zhani reported that a maliciously crafted vp9 format video could be used to trigger a buffer overflow while parsing the file. This leads to a potentially exploitable crash due to a flaw in the libvpx library.
In general this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
