A security flaw has been discovered in Nothings stbimage up to 2.30. This affects the function stbigifloadnext of the file stbimage.h of the component Multi-frame GIF File Handler. The manipulation results in heap-based buffer overflow. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

stbimage.h and stbvorbis libraries contain several memory access violations of different severity.
