Descriptions

Git before 1.8.5.6, 1.9.x before 1.9.5, 2.0.x before 2.0.5, 2.1.x before 2.1.4, and 2.2.x before 2.2.1 on Windows and OS X; Mercurial before 3.2.3 on Windows and OS X; Apple Xcode before 6.2 beta 3; mine all versions before 08-12-2014; libgit2 all versions up to 0.21.2; Egit all versions before 08-12-2014; and JGit all versions before 08-12-2014 allow remote Git servers to execute arbitrary commands via a tree containing a crafted .git/config file with (1) an ignorable Unicode codepoint, (2) a git~1/config representation, or (3) mixed case that is improperly handled on a case-insensitive filesystem.

Git versiones anteriores a 1.8.5.6, versiones 1.9.x anteriores a 1.9.5, versiones 2.0.x anteriores a 2.0.5, versiones 2.1.x anteriores a 2.1.4 y versiones 2.2.x anteriores a 2.2.1 en Windows y OS X; Mercurial versiones anteriores a 3.2.3 en Windows y OS X; Apple Xcode versiones anteriores a 6.2 beta 3; mine todas las versiones antes del 08-12-2014; libgit2 todas las versiones hasta 0.21. 2; Egit todas las versiones anteriores al 08-12-2014; y JGit todas las versiones anteriores al 08-12-2014 permiten a los servidores Git remotos ejecutar comandos arbitrarios por medio de un árbol que contiene un archivo .git/config diseñado con (1) un punto de código Unicode ignorable, (2) una representación git~1/config, o (3) mayúsculas y minúsculas que no son manejadas apropiadamente en un sistema de archivos insensible a mayúsculas y minúsculas

It was reported that git, when used as a client on a case-insensitive filesystem, could allow the overwrite of the.git/config file when the client performed a git pull. Because git permitted committing.Git/config , on the pull this would replace the user's.git/config. If this malicious config file contained defined external commands (such as for invoking and editor or an external diff utility) it could allow for the execution of arbitrary code with the privileges of the user running the git client.
