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
We have some possible fixes in our bug [1], but be cautious - these are not fully vetted yet.
[1] https://bugzilla.redhat.com/show_bug.cgi?id=1227243
Use CVE-2015-4588 for this new issue. (The two issues were disclosed at different times by different persons. CVE-2015-0848 is about a missing bits-per-pixel factor in a calculation. CVE-2015-4588 is about a loop that can proceed past the end of its output array.) - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJVf4pCAAoJEKllVAevmvmssL4H/A31/XONQy1Fc7/Ko6Nvy09R bBe98kCx4HTZxDONT/WT7QWXFZ1BJH5p9e+MSnTpNUkltaTtCp9PNCRnD21S6YSu MrbopCukDvOtifSfBEi2qWX/U6qB+Rqs1EhexK3TuUVT4L+KqxOzBkcRx+o3zmKQ m3iTWSAq7rVz7HUPI0lnVwpJyDmFrBZZK6KH3M0Cz95EjAeAF1HHEAkVkMn6CO9i 3sAGCSJexFzXp6TSOfwRiHpttUr4+yt6JIF+eCRKY2dPxdt3Q9O0/jFfScQ6CJNm hMHjpNJyt0i/ShLxy05sV8glhy6gk1vpw0QBIAITVXZlR+CAOTa7tZoqWRCaR7I= =bRPB -----END PGP SIGNATURE-----
