Git: Arbitrary command execution

Git: Arbitrary command execution An attacker could execute arbitrary commands via Git repositories in a case-insensitive or case-normalizing filesystem. git 2015-09-24 2015-09-24 532984 remote 1.8.5.6 1.9.5 2.0.5 2.0.5

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

A vulnerability in Git causing Git-compatible clients that access case-insensitive or case-normalizing filesystems to overwrite the .git/config when cloning or checking out a repository, leading to execution of arbitrary commands.

An attacker can execute arbitrary commands on a client machine that clones a crafted malicious Git tree.

There is no known workaround at this time.
