Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to usage of an untrusted search path in Git GUI on Windows. A malicious repository can ship versions of sh.exe or typical textconv filter programs such as astextplain. On Windows, path lookup can find such executables in the worktree. These programs are invoked when the user selects "Git Bash" or "Browse Files" from the menu.

Note, the vulnerability affects Windows installations only. 

Mitigation
Install updates from vendor's website.
