Description

Security researcher Aki Helin used the Address Sanitizer tool to find a buffer overflow write when rendering some WebGL content. This leads to a potentially exploitable crash.

In general this flaw cannot be exploited through email in the Thunderbird product, but is potentially a risk in browser or browser-like contexts.
