A heap-buffer-overflow vulnerability exists in the nothings stb TrueType library, up to version 1.26, that is used for parsing TrueType font files. The vulnerability exists in the stbttGetGlyphShapeTT() function within the nothings stbtruetype.h library when parsing malformed TTF (TrueType Font) files. The vulnerability resides in the glyph data parsing path. An attacker can craft a malformed TTF file with an inflated endPtsOfContours value and truncate the remaining glyph data. When an application utilizing stbtruetype.h (such as various game engines or graphics software) attempts to load, bake, or render this malformed font via stbttGetGlyphShape(), the parser will attempt to read past the end of the glyph data buffer, triggering the out-of-bounds read.

The vendor was contacted early about this disclosure but did not respond in any way.

A vulnerability has been found in Nothings stb up to 2.30. This issue affects the function stbigifloadnext in the library stbimage.h of the component GIF Decoder. Such manipulation leads to denial of service. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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.

A weakness has been identified in Nothings stb up to 2.30. This impacts the function stbiloadgifmain of the file stbimage.h of the component Multi-frame GIF File Handler. This manipulation causes double free. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

stbimage.h (aka the stb image loader) 2.23, as used in libsixel and other products, has a heap-based buffer over-read in stbiloadmain.

A heap-based buffer overflow vulnerability exists in the comment functionality of stb vorbis.c v1.22. A specially crafted .ogg file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.

Nothings stb 2.28 was discovered to contain a Null Pointer Dereference via the function stbiconvertformat. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted pic file.

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

An issue was discovered in stb stbimage.h 1.33 through 2.27. The HDR loader parsed truncated end-of-file RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused denial of service in applications using stbimage by submitting crafted HDR files.

An issue was discovered in stb stbimage.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stbimage, or read up to 1024 bytes of non-consecutive heap data without control over the read location.
