Description: A vulnerability was reported in GIT. A remote user can cause arbitrary code to be executed on the target user's system.
A remote user can create a repository with a specially crafted pathname that is longer than PATH_MAX on the target user's system.
Then, when the target user runs git-diff on the repository, a buffer overflow may occur in in diff_addremove() and diff_change(),
executing arbitrary code on the target user's system. The code will run with the privileges of the target user.
|
Impact: A remote user can create a pathname that, when processed by the target user with git-diff, will execute arbitrary code on the target user's system.
|
Solution: The vendor has issued a fix (1.5.6.4).
