Hi,
The following vulnerabilities were published for libstb.
CVE-2021-42715[0]:
| 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-2021-42716[1]:
| 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.
