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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Buffer overflow vulnerability in function stbi__extend_receive in stb_image.h in stb 2.26 via a crafted     JPEG file. (CVE-2021-28021)

  - 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. (CVE-2021-42715)
