Package : libstb Version : 0.0~git20200713.b42009b+ds-1+deb11u1 CVE ID : CVE-2021-28021 CVE-2021-37789 CVE-2021-42715 CVE-2022-28041 CVE-2022-28042

Several vulnerabilities were discovered in libstb, single-file image and audio processing libraries for C/C++.

CVE-2021-28021

Buffer overflow vulnerability in function stbi__extend_receive in stb_image.h. Can be exploited with a crafted JPEG file.

CVE-2021-37789

a heap-based buffer over in stbi__jpeg_load, leading to Information Disclosure or Denial of Service.

CVE-2021-42715

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.

CVE-2022-28041

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

a heap-based use-after-free via the function stbi__jpeg_huff_decode.

For Debian 11 bullseye, these problems have been fixed in version 0.0~git20200713.b42009b+ds-1+deb11u1.

We recommend that you upgrade your libstb packages.
