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.

For the detailed security status of openjpeg2 please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
