There's another issue related to the RLE decoding. DecodeImage() does not check that the run-length "count" fits into the total size of the image, which can lead to a heap-based buffer overflow. I've not assigned a CVE ID to this (mainly because I'm not sure if this warrants a new CVE or should be bundled with CVE-2015-0848, so I leave that up to the CVE experts on the list). We have some possible fixes in our bug [1], but be cautious - these are not fully vetted yet. So far, however, they look fine to me. [1] https://bugzilla.redhat.com/show_bug.cgi?id=1227243
Any update on a possible CVE for this additional issue? Thanks, -- Stefan Cornelius / Red Hat Product Security
