Uclouvain: >> Openjpeg >> 2.4.0 Security Vulnerabilities
OpenJPEG is an open-source JPEG 2000 codec. In OpenJPEG 2.5.3 and earlier, a call to opj_jp2_read_header may lead to OOB heap memory write when the data stream p_stream is too short and p_image is not initialized.

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.

A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.

Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when the attacker uses the command line option "-ImgDir" on a directory that contains 1048576 files.
