CVE ID         : CVE-2020-27842 CVE-2020-27843 CVE-2021-29338 CVE-2022-1122

Multiple vulnerabilities have been discovered in openjpeg2, the open-source
JPEG 2000 codec.

CVE-2020-27842

    Null pointer dereference through specially crafted input. The highest impact
    of this flaw is to application availability.


CVE-2020-27843

    The flaw allows an attacker to provide specially crafted input to the
    conversion or encoding functionality, causing an out-of-bounds read. The
    highest threat from this vulnerability is system availability.


CVE-2021-29338

    Integer overflow allows remote attackers to crash the application, causing a
    denial of service. This occurs when the attacker uses the command line
    option "-ImgDir" on a directory that contains 1048576 files.


CVE-2022-1122

    Input directory with a large number of files can lead to a segmentation
    fault and a denial of service due to a call of free() on an uninitialized
    pointer.

For Debian 9 stretch, these problems have been fixed in version
2.1.2-1.1+deb9u7.

We recommend that you upgrade your openjpeg2 packages.
