Summary

Details

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. All versions are vulnerable to Heap-based Buffer Overflow through the XWD parser's use of the bytesperline value. The value os read directly from the file as the read size in io->strictread(), and is never compared to the actual size of the destination buffer. An attacker can provide an XWD file with an arbitrarily large bytesper_line, causing a massive write operation beyond the buffer heap allocated for the image pixels. The issue did not have a fix at the time of publication.
