8Fixes since v2.43.6
9-------------------
10
11 * CVE-2025-27613, Gitk:
12
13 When a user clones an untrusted repository and runs Gitk without
14 additional command arguments, any writable file can be created and
15 truncated. The option "Support per-file encoding" must have been
16 enabled. The operation "Show origin of this line" is affected as
17 well, regardless of the option being enabled or not.
18
19 * CVE-2025-27614, Gitk:
20
21 A Git repository can be crafted in such a way that a user who has
22 cloned the repository can be tricked into running any script
23 supplied by the attacker by invoking `gitk filename`, where
24 `filename` has a particular structure.
25
26 * CVE-2025-46334, Git GUI (Windows only):
27
28 A malicious repository can ship versions of sh.exe or typical
29 textconv filter programs such as astextplain. On Windows, path
30 lookup can find such executables in the worktree. These programs
31 are invoked when the user selects "Git Bash" or "Browse Files" from
32 the menu.
33
34 * CVE-2025-46835, Git GUI:
35
36 When a user clones an untrusted repository and is tricked into
37 editing a file located in a maliciously named directory in the
38 repository, then Git GUI can create and overwrite any writable
39 file.
40
41 * CVE-2025-48384, Git:
42
43 When reading a config value, Git strips any trailing carriage
44 return and line feed (CRLF). When writing a config entry, values
45 with a trailing CR are not quoted, causing the CR to be lost when
46 the config is later read. When initializing a submodule, if the
47 submodule path contains a trailing CR, the altered path is read
48 resulting in the submodule being checked out to an incorrect
49 location. If a symlink exists that points the altered path to the
50 submodule hooks directory, and the submodule contains an executable
51 post-checkout hook, the script may be unintentionally executed
52 after checkout.
53
54 * CVE-2025-48385, Git:
55
56 When cloning a repository Git knows to optionally fetch a bundle
57 advertised by the remote server, which allows the server-side to
58 offload parts of the clone to a CDN. The Git client does not
59 perform sufficient validation of the advertised bundles, which
60 allows the remote side to perform protocol injection.
61
62 This protocol injection can cause the client to write the fetched
63 bundle to a location controlled by the adversary. The fetched
64 content is fully controlled by the server, which can in the worst
65 case lead to arbitrary code execution.
66
67 * CVE-2025-48386, Git:
68
69 The wincred credential helper uses a static buffer (`target`) as a
70 unique key for storing and comparing against internal storage. This
71 credential helper does not properly bounds check the available
72 space remaining in the buffer before appending to it with
73 `wcsncat()`, leading to potential buffer overflows.
