"The remote host is affected by the vulnerability described in GLSA-202209-04 (OpenJPEG: Multiple Vulnerabilities)

  - 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. (CVE-2021-29338)

  - 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. (CVE-2022-1122)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
