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

  - 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)

  - There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to     provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The     greatest impact from this flaw is to application availability. (CVE-2020-27841)

  - There's a flaw in src/lib/openjp2/pi.c of openjpeg in versions prior to 2.4.0. If an attacker is able to     provide untrusted input to openjpeg's conversion/encoding functionality, they could cause an out-of-bounds     read. The highest impact of this flaw is to application availability. (CVE-2020-27845)

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 issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to     provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The     greatest impact from this flaw is to application availability. (CVE-2020-27841)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of openjpeg2 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2020-27841 advisory.

  - There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to     provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The     greatest impact from this flaw is to application availability. (CVE-2020-27841)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4686-1 advisory.

    It was discovered that Ghostscript incorrectly handled certain image files. If a user or automated system     were tricked into processing a specially crafted file, a remote attacker could use this issue to cause     Ghostscript to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4685-1 advisory.

    It was discovered that OpenJPEG incorrectly handled certain image data. An attacker could use this issue     to cause OpenJPEG to crash, leading to a denial of service, or possibly execute arbitrary code.

  - A heap-buffer overflow was found in the way openjpeg2     handled certain PNG format files. An attacker could use     this flaw to cause an application crash or in some     cases execute arbitrary code with the permission of the     user running such an application.(CVE-2020-27814)

  - A flaw was found in OpenJPEG's encoder. This flaw     allows an attacker to pass specially crafted x,y offset     input to OpenJPEG to use during encoding. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2020-27823)
