FKIE_CVE-2021-46822

Vulnerability from fkie_nvd - Published: 2022-06-18 16:15 - Updated: 2024-11-21 06:34
Summary
The PPM reader in libjpeg-turbo through 2.0.90 mishandles use of tjLoadImage for loading a 16-bit binary PPM file into a grayscale buffer and loading a 16-bit binary PGM file into an RGB buffer. This is related to a heap-based buffer overflow in the get_word_rgb_row function in rdppm.c.
