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. Se ha detectado un problema en stb stb_image.h versión 2.27. El cargador de PNM interpretaba incorrectamente los archivos PGM de 16 bits como de 8 bits cuando los convertía a RGBA, conllevando a un desbordamiento del búfer cuando se reinterpreta posteriormente el resultado como un búfer de 16 bits. • https://github.com/nothings/stb/issues/1166 https://github.com/nothings/stb/issues/1225 https://github.com/nothings/stb/pull/1223 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3TDGZFLBOP27LZKLH45WQLSNPSPP7S7Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AF2CNP4FVC6LDKNOO4WDCGNDYIP3MPK6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEGXBDEMTFGINETMJENBZ6SCHVEJQJSY https://lists.fedoraproject.org • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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. Se ha detectado un problema en stb stb_image.h versiones 1.33 hasta 2.27. El cargador HDR analizaba líneas de exploración RLE truncadas al final del archivo como una secuencia infinita de ejecuciones de longitud cero. • https://github.com/nothings/stb/issues/1224 https://github.com/nothings/stb/pull/1223 https://lists.debian.org/debian-lts-announce/2023/01/msg00045.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3TDGZFLBOP27LZKLH45WQLSNPSPP7S7Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AF2CNP4FVC6LDKNOO4WDCGNDYIP3MPK6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BEGXBDEMTFGINETMJENBZ6SCHVEJQJSY https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
