Git Hash Chain Malleability

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
Git commit signing is widely entrusted to serve as evidence that a commit hash uniquely and immutably identifies a specific piece of signed content. We show this invariant does not hold. Given any signed commit, an attacker without access to the signing key, and without breaking SHA2 can produce a second, distinct commit with an identical tree, identical metadata, a valid signature, and a ...
