CVE-2021-42715: An issue was discovered in stb stb_image.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 stb_image by submitting crafted HDR files. PR Patch: https://github.com/nothings/stb/pull/1223 CVE-2021-42716: An issue was discovered in stb stb_image.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 stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location. PR Patch: https://github.com/nothings/stb/pull/1223 I'm absolutely baffled as to why these versions are in the CVE descriptions, only ALT Linux and something called "Rosa" seem to be using this scheme, but I don't see why they might be getting it from. Neither patch is accepted yet. CVE-2022-28048 (https://github.com/nothings/stb/pull/1297): https://github.com/nothings/stb/issues/1293 STB v2.27 was discovered to contain an integer shift of invalid size in the component stbi__jpeg_decode_block_prog_ac. CVE-2022-28041 (https://github.com/nothings/stb/pull/1297): https://github.com/nothings/stb/issues/1292 stb_image.h v2.27 was discovered to contain an integer overflow via the function stbi__jpeg_decode_block_prog_dc. This vulnerability allows attackers to cause a Denial of Service (DoS) via unspecified vectors. CVE-2022-28042 (https://github.com/nothings/stb/issues/1289): https://github.com/nothings/stb/pull/1297 stb_image.h v2.27 was discovered to contain an heap-based use-after-free via the function stbi__jpeg_huff_decode. None of these patches accepted, either. CVE-2021-37789 (https://github.com/nothings/stb/issues/1178): stb_image.h 2.27 has a heap-based buffer over in stbi__jpeg_load, leading to Information Disclosure or Denial of Service. |
