Summary
gix-transport code execution vulnerability
Details

The gix-transport crate prior to the patched version 0.36.1 would allow attackers to use malicious ssh clone URLs to pass arbitrary arguments to the ssh program, leading to arbitrary code execution.

PoC: gix clone 'ssh://-oProxyCommand=open$IFS-aCalculator/foo'

This will launch a calculator on OSX.
