Debian: New git-core packages fix buffer overflow
LinuxSecurity.com: Multiple vulnerabilities have been identified in git-core, the core of the git distributed revision control system. Improper path length limitations in git's diff and grep functions, in combination with maliciously crafted repositories or changes, could enable a stack buffer overflow and potentially the execution of arbitrary code.

GIT-PATCH-ID(1) 						    Git Manual							   GIT-PATCH-ID(1)

NAME

       git-patch-id - Compute unique ID for a patch

SYNOPSIS

       git patch-id < <patch>

DESCRIPTION

       A "patch ID" is nothing but a SHA1 of the diff associated with a patch, with whitespace and line numbers ignored. As such, it's "reasonably
       stable", but at the same time also reasonably unique, i.e., two patches that have the same "patch ID" are almost guaranteed to be the same
       thing.

       IOW, you can use this thing to look for likely duplicate commits.

       When dealing with git diff-tree output, it takes advantage of the fact that the patch is prefixed with the object name of the commit, and
       outputs two 40-byte hexadecimal strings. The first string is the patch ID, and the second string is the commit ID. This can be used to make
       a mapping from patch ID to commit ID.

OPTIONS

       <patch>
	   The diff to create the ID of.
