Descriptions

contrib/completion/git-prompt.sh in Git before 1.9.3 does not sanitize branch names in the PS1 variable, allowing a malicious repository to cause code execution.

Contrib/completion/git-prompt.sh en Git en versiones anteriores a 1.9.3 no desinfecta nombres de sucursales en la variable PS1, permitiendo que un repositorio malicioso cause la ejecución de código.

It was found that the git-prompt.sh script shipped with git failed to correctly handle branch names containing special characters. A specially crafted git repository could use this flaw to execute arbitrary commands if a user working with the repository configured their shell to include repository information in the prompt.
