Subject: imagemagick: memory allocation failure in AcquireMagickMemory (memory.c) (incomplete fix for CVE-2016-8862 and CVE-2016-8866)
It is probably one of the last issues reported by me on imagemagick because it is always a fight make upstream able to reproduce the issue, however I'm not doing anything special.
Description:
imagemagick is a software suite to create, edit, compose, or convert bitmap images.
Another round of fuzzing pointed out that the memory allocation failure I discovered, known as CVE-2016-8862 and CVE-2016-8866 is still reproducible in the 7.0.4.9 version.
As usual, the upstream security policy are enabled.
The interesting part of the ASan stacktrace(not full because is a copy past of the one in the previous post):
