Description Vladimir Vasilev 2026-10-15 18:00:13 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

DevIL through 1.8.0 contains a heap-based buffer overflow in iGetPalette() in il_gif.cpp that allows attackers to write beyond a 768-byte palette buffer when loading GIF images. Attackers can supply a crafted two-frame GIF whose second frame uses disposal method 1 with a local colour table, writing up to 384 controlled bytes past the heap allocation and possibly executing code.
