stb stb_image.h has an unspecified vulnerability

stb is a single-file public domain library for C/C. stbimage.h is one of the image loaders. stb stbimage.h contains a security vulnerability that stems from the HDR loader parsing truncated file-tailed RLE scan lines into an infinitely long zero-length sequence. An attacker could cause a denial o...

CVE-2021-42716

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...
