Git vulnerabilities

Git versions before 2.10.5, 2.11.x before 2.11.4, 2.12.x before 2.12.5, 2.13.x before 2.13.6, and 2.14.x before 2.14.2 use unsafe Perl scripts to support subcommands, allowing attackers to execute arbitrary OS commands via shell metacharacters in a module name.

Git defines a line-based protocol used to exchange information between Git and Git credential helpers. Some ecosystems (most likely those using this protocol) may be vulnerable to attacks related to this protocol.

When Git asks for credentials via a terminal prompt (without using a credential helper), it prints the host name for which the credentials are requested. This may lead to unintended disclosure of the host name.

Git is a fast, scalable, distributed revision control system. When cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload.

In Git versions before 2.3.10, 2.4.x before 2.4.10, 2.5.x before 2.5.4, and 2.6.x before 2.6.1, there is a vulnerability that does not properly restrict allowed protocols in remote helper programs. This may allow remote attackers to execute arbitrary code via a URL in a .gitmodules file or other unknown sources in a submodule.

Integer overflow in Git before version 2.7.4 allows remote attackers to execute arbitrary code via (1) long filename or (2) many nested trees, leading to a heap-based buffer overflow.

In git versions before 2.7.4, there is a bug in revision.c that uses an incorrect integer data type. This allows remote attackers to execute arbitrary code via (1) long filenames or (2) many nested trees, leading to a heap-based buffer overflow.

Gita versions up to 1.11 are vulnerable to unauthenticated local file inclusion.
