Synopsis
The remote Red Hat host is missing one or more security updates for mercurial.Description
The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2489 advisory.Mercurial is a fast, lightweight source control management system designed for efficient handling of very large distributed projects.
Security Fix(es):
* A vulnerability was found in the way Mercurial handles path auditing and caches the results. An attacker could abuse a repository with a series of commits mixing symlinks and regular files/directories to trick Mercurial into writing outside of a given repository. (CVE-2017-1000115)
* A shell command injection flaw related to the handling of ssh URLs has been discovered in Mercurial.
This can be exploited to execute shell commands with the privileges of the user running the Mercurial client, for example, when performing a checkout or update action on a sub-repository within a malicious repository or a legitimate repository containing a malicious commit. (CVE-2017-1000116)
Red Hat would like to thank the Mercurial Security Team for reporting CVE-2017-1000115 and the Subversion Team for reporting CVE-2017-1000116.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
