Summary

Maliciously crafted Git server replies can cause DoS on go-git clients

Details

Impact

A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.11. This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in go-git clients.

Applications using only the in-memory filesystem supported by go-git are not affected by this vulnerability. This is a go-git implementation issue and does not affect the upstream git cli.

Patches

Users running versions of go-git from v4 and above are recommended to upgrade to v5.11 in order to mitigate this vulnerability.

Workarounds

In cases where a bump to the latest version of go-git is not possible, we recommend limiting its use to only trust-worthy Git servers.
