A race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.

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

  - A race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an     attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.
    (CVE-2019-11922)

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 remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5593-1 advisory.

  - A race condition in the one-pass compression functions of Zstandard prior to version 1.3.8 could allow an     attacker to write bytes out of bounds if an output buffer smaller than the recommended size was used.
    (CVE-2019-11922)

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