Summary: An update for mercurial is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: 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. 4.
