Scientific Linux Security Update : mercurial on SL7.x x86_64
High Nessus Plugin ID 102676
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionSecurity 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.
- 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.
SolutionUpdate the affected packages.
