A buffer overflow was discovered in Graphviz, which could potentially result in the execution of arbitrary code when processing a malformed file.

The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2021:4256 advisory.

  - graphviz: off-by-one in parse_reclbl() in lib/common/shapes.c (CVE-2020-18032)

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 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5971-1 advisory.

    It was discovered that graphviz contains null pointer dereference vulnerabilities. Exploitation via a     specially crafted input file can cause a denial of service. This issue only affected Ubuntu 18.04 LTS.

The version of graphviz installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2020-18032 advisory.

  - Buffer Overflow in Graphviz Graph Visualization Tools from commit ID f8b9e035 and earlier allows remote     attackers to execute arbitrary code or cause a denial of service (application crash) by loading a crafted     file into the lib/common/shapes.c component. (CVE-2020-18032)

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

This update for graphviz fixes the following issues :

  - CVE-2020-18032: Fixed possible remote code execution via     buffer overflow (bsc#1185833).

This update was imported from the SUSE:SLE-15:Update update project.

According to the version of the graphviz packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - Buffer Overflow in Graphviz Graph Visualization Tools     from commit ID f8b9e035 and earlier allows remote     attackers to execute arbitrary code or cause a denial     of service (application crash) by loading a crafted     file into the 'lib/common/shapes.c'     component.(CVE-2020-18032)

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.
