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.

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. (CVE-2021-42716)
