Description

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

  • Mercurial is a fast, lightweight source control management system designed for efficient handling of very large distributed projects.

  • Security fix(es):

  • Mercurial version 4.5 and earlier contains a Incorrect Access Control (CWE-285) vulnerability in Protocol server that can result in Unauthorized data access. This attack appear to be exploitable via network connectivity. (CVE-2018-1000132)

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.
