MEDIUM 5.5EPSS 1.05%

Does this matter?

Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.

Description

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.
