"According to the versions of the openjpeg2 packages installed, the EulerOS installation on the remote host is affected
by the following 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)

advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
