Der er fundet flere sårbarheder i git-core, kernen i reversionsstyringssystemet git. Ukorrekte stilængdebegrænsninger i git's diff- og grep-funktioner, kombineret med ondsindet fremstillede arkiver (repositories) eller ændringer, kunne muliggøre stakbufferoverløb og potentielt udførelse af vilkårlig kode.
