Git v2.30.8 Release Notes
2+
=========================
3+
4+
This release addresses the security issues CVE-2023-22490 and
5+
CVE-2023-23946.
6+
7+
8+
Fixes since v2.30.7
9+
-------------------
10+
11+
* CVE-2023-22490:
12+
13+
Using a specially-crafted repository, Git can be tricked into using
14+
its local clone optimization even when using a non-local transport.
15+
Though Git will abort local clones whose source $GIT_DIR/objects
16+
directory contains symbolic links (c.f., CVE-2022-39253), the objects
17+
directory itself may still be a symbolic link.
18+
19+
These two may be combined to include arbitrary files based on known
20+
paths on the victim's filesystem within the malicious repository's
21+
working copy, allowing for data exfiltration in a similar manner as
22+
CVE-2022-39253.
23+
24+
* CVE-2023-23946:
25+
26+
By feeding a crafted input to "git apply", a path outside the
27+
working tree can be overwritten as the user who is running "git
28+
apply".
29+
30+
* A mismatched type in `attr.c::read_attr_from_index()` which could
31+
cause Git to errantly reject attributes on Windows and 32-bit Linux
32+
has been corrected.
33+
34+
Credit for finding CVE-2023-22490 goes to yvvdwf, and the fix was
35+
developed by Taylor Blau, with additional help from others on the
36+
Git security mailing list.
37+
38+
Credit for finding CVE-2023-23946 goes to Joern Schneeweisz, and the
39+
fix was developed by Patrick Steinhardt.
40+
41+
42+
Johannes Schindelin (1):
43+
attr: adjust a mismatched data type
44+
45+
Patrick Steinhardt (1):
46+
apply: fix writing behind newly created symbolic links
47+
48+
Taylor Blau (3):
49+
t5619: demonstrate clone_local() with ambiguous transport
50+
clone: delay picking a transport until after get_repo_path()
51+
dir-iterator: prevent top-level symlinks without FOLLOW_SYMLINKS

* We already try to detect whether files are beyond a symlink in our

* up-front checks. But in the case where symlinks are created by any
4414+

4415+

4416+
* in fact is one. We thus repeat the check for symlinks here.
4417+
*
4418+
* Note that this does not make the up-front check obsolete as the
4419+
* failure mode is different:
4420+
*
4421+
* - The up-front checks cause us to abort before we have written
4422+
* anything into the working directory. So when we exit this way the
4423+
* working directory remains clean.

4425+
* - The checks here happen in the middle of the action where we have
4426+
* already started to apply the patch. The end result will be a dirty

* working directory.
4428+
*
4429+
* Ideally, we should update the up-front checks to catch what would
4430+
* happen when we apply the patch before we damage the working tree.
4431+
* We have all the information necessary to do so. But for now, as a
4432+
* part of embargoed security work, having this check would serve as a
4433+
* reasonable first step.
