Description
Fredrik 'Flonka' Lönnqvist discovered an issue with image
decoding in RasterImage caused by continued use of discarded
images. This could allow for the writing to unowned memory and a potentially
exploitable crash.
In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled in mail, but is potentially a risk in browser or browser-like contexts.
