Detailsinfo

A vulnerability, which was classified as critical, has been found in libjpeg-turbo up to 2.0.90. Affected by this issue is the function get_word_rgb_row of the file rdppm.c of the component PPM Reader. The manipulation with an unknown input leads to a heap-based overflow vulnerability.
