Описание
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.
A heap-based buffer overflow vulnerability was found in libjpeg-turbo in the get_word_rgb_row() function in rdppm.c. The flaw occurs when the PPM reader in libjpeg-turbo mishandles use of the tjLoadImage() function for loading a 16-bit binary PPM file into a grayscale uncompressed image buffer and then loading a 16-bit binary PGM file into an RGB uncompressed image buffer. This flaw allows a remote attacker to persuade a victim to open a specially-crafted file, causing the application to crash.
Отчет
The only way that users could potentially encounter these issues is through the tjLoadImage() function. TJBench and cjpeg are unaffected. RHEL-8 ships libjpeg-turbo v1.5.3 which does not include vulnerable tjLoadImage() functionality.
