Re: [ANNOUNCE] Git v2.7.4 (and updates to older maintenance tracks)

The latest maintenance release Git v2.7.4 is now available at the
usual places.  The same set of bugfix patches from the current
'master' have been backported to older maintenance tracks and are
available as v2.4.11, v2.5.5 and v2.6.6.  These are to fix a heap
corruption / buffer overflow bug and users are strongly encouraged
to upgrade.  The fix has already been in the release candidate
v2.8.0-rc3 as well.

The tarballs are found at:

   https://www.kernel.org/pub/software/scm/git/

The following public repositories all have a copy of the 'v2.7.4'
tag and the 'maint' branch that the tag points at:

Git v2.7.4 Release Notes
========================

Fixes since v2.7.3
------------------

* Bugfix patches were backported from the 'master' front to plug heap
  corruption holes, to catch integer overflow in the computation of
  pathname lengths, and to get rid of the name_path API.  Both of
  these would have resulted in writing over an under-allocated buffer
  when formulating pathnames while tree traversal.

----------------------------------------------------------------

Changes since v2.7.3 are as follows:

Jeff King (7):
     add helpers for detecting size_t overflow
     tree-diff: catch integer overflow in combine_diff_path allocation
     http-push: stop using name_path
     show_object_with_name: simplify by using path_name()
     list-objects: convert name_path to a strbuf
     list-objects: drop name_path entirely
     list-objects: pass full pathname to callbacks

Junio C Hamano (4):
     Git 2.4.11
     Git 2.5.5
     Git 2.6.6
     Git 2.7.4

FYI,

2.7.4 fails to build on FreeBSD 9.x, that uses by default gcc 4.2.1. I’ve fixed it adding an extra dependency to make force it to require gcc 4.8+. Here is the output:
