CVE-2021-46822
Last modified
CVE-2021-46822 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 1.00% chance of exploitation in the next 30 days.
