Mozilla community member Ms2ger discovered that some
DOMSVGZoomEvent functions are used without being properly
initialized, causing uninitialized memory to be used when they are called by web
content. This could lead to a information leakage to sites depending on the
contents of this uninitialized memory.
In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled, but are potentially a risk in browser or browser-like contexts.
