Closed Bug 1243816 (CVE-2016-2796) Opened 6 years ago Closed 6 years ago
graphite2: heap-buffer-overflow write in [@graphite2::vm::Machine::Code::Code]
This was found while fuzzing graphite2 1.3.5 (and is in 1.3.4) This is likely sec-critical.
Tracking since this likely affects all channels including esr38 and it's sec-critical.
There's a patch in bug 1243843 (awaiting testing) that may well fix this.
fixed upstream in a8b3ac2aed0eb132cd80efe7de88f8153e73c829
Does that mean we can close this bug? Tyson can you or someone else verify this is fixed?
(In reply to Liz Henry (:lizzard) (needinfo? me) from comment #8) > Does that mean we can close this bug? Tyson can you or someone else verify > this is fixed? I believe so based on Martin's comment, but would appreciate having it verified on our latest builds.
This crash is still reproducible with the latest fixes (e569e28d83491fedb31b9220493f3c07f6ec6d80)
Martin, can you look into this again, please?
I have a potential fix, needs review internally. Should be fixed in 24hrs. This bug would be hard to make anything of.
This and all friends fixed upstream. Sorry, I forgot to do asan testing last time around :( This time they all run asan clean on 64bit.
