[ASA-201708-7] mercurial: multiple issues
Arch Linux Security Advisory ASA-201708-7 ========================================= Severity: Critical Date : 2017-08-12 CVE-ID : CVE-2017-1000115 CVE-2017-1000116 Package : mercurial Type : multiple issues Remote : Yes Link : Summary ======= The package mercurial before version 4.2.3-1 is vulnerable to multiple issues including arbitrary command execution and arbitrary filesystem access. Resolution ========== Upgrade to 4.2.3-1. # pacman -Syu "mercurial>=4.2.3-1" The problems have been fixed upstream in version 4.2.3. Workaround ========== None. Description =========== - CVE-2017-1000115 (arbitrary filesystem access) Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository. - CVE-2017-1000116 (arbitrary command execution) Mercurial < 4.3 was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed. Impact ====== A remote attacker can execute arbitrary command on the affected host by tricking a user into executing a hg command. A remote attacker can use crafted commits mixing symlinks and regular files to get access to files outside the repository. References ==========
