Updated git packages fix security vulnerability

It was reported that git, when used as a client on a case-insensitive filesystem, could allow the overwrite of the .git/config file when the client performed a "git pull". Because git permitted committing .Git/config (or any case variation), on the pull this would replace the user's .git/config. If this malicious config file contained defined external commands (such as for invoking and editor or an external diff utility) it could allow for the execution of arbitrary code with the privileges of the user running the git client (CVE-2014-9390).

git vulnerability

Matt Mackall and Augie Fackler discovered that Git incorrectly handled certain filesystem paths. A remote attacker could possibly use this issue to execute arbitrary code if the Git tree is stored in an HFS+ or NTFS filesystem. The remote attacker would need write access to a Git repository that the victim pulls from.
