"According to the versions of the openjpeg2 package installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

  - OpenJPEG 2.3.0 has a NULL pointer dereference for 'red' in the imagetopnm function of jp2/convert.c
    (CVE-2018-18088)

  - Division-by-zero vulnerabilities in the functions pi_next_pcrl, pi_next_cprl, and pi_next_rpcl in
    openmj2/pi.c in OpenJPEG through 2.3.0 allow remote attackers to cause a denial of service (application
    crash). (CVE-2018-20845)

  - In OpenJPEG 2.3.0, there is an integer overflow vulnerability in the opj_t1_encode_cblks function
    (openjp2/t1.c). Remote attackers could leverage this vulnerability to cause a denial of service via a
    crafted bmp file. (CVE-2018-5727)

  - In OpenJPEG 2.3.1, there is excessive iteration in the opj_t1_encode_cblks function of openjp2/t1.c.
    Remote attackers could leverage this vulnerability to cause a denial of service via a crafted bmp file.
    This issue is similar to CVE-2018-6616. (CVE-2019-12973)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
