CVE-2022-24106 Xpdf prior to 4.04 had a DCT (JPEG) decoder bug that allowed the 'interleaved' flag to be changed after the first scan of the image, which led to a vulnerability in Stream.cc.
The DCT (JPEG) decoder in Xpdf prior to 4.04 allowed the 'interleaved' flag to be changed before the first scan of the image, leading to an integer-related vulnerability in Stream.cc. This issue was fixed in version 4.04 by changing the DCT (JPEG) decoder to always process images in order (first scan, last scan). Upgrading software to 4.04 or later is recommended.
