Name of the Vulnerable Software and Affected Versions libjpeg-turbo versions 2.0.90 and earlier

Description The issue is related to a heap-based buffer overflow in the get word rgb row function in rdppm.c, which occurs when using tjLoadImage to load a 16-bit binary PPM file into a grayscale buffer and a 16-bit binary PGM file into an RGB buffer.

Recommendations For libjpeg-turbo versions 2.0.90 and earlier, update to a version later than 2.0.90 to resolve the issue. As a temporary workaround, consider restricting the use of tjLoadImage for loading 16-bit binary PPM and PGM files until a patch is available. Avoid using the get word rgb row function in rdppm.c with untrusted input until the issue is resolved.
