Read the announcement: https://lwn.net/ml/all/xmqq5xg2wrd1.fsf@gitster.g/ This fixes the following vulnerabilities: - CVE-2025-27613 (Gitk): When a user clones an untrusted repository and runs Gitk without additional command arguments, any writable file can be created and truncated. The option "Support per-file encoding" must have been enabled. The operation "Show origin of this line" is affected as well, regardless of the option being enabled or not. https://www.cve.org/CVERecord?id=CVE-2025-27613 - CVE-2025-27614 (Gitk): A Git repository can be crafted in such a way that a user who has cloned the repository can be tricked into running any script supplied by the attacker by invoking `gitk filename`, where `filename` has a particular structure. https://www.cve.org/CVERecord?id=CVE-2025-27614 - CVE-2025-46835 (Git GUI): When a user clones an untrusted repository and is tricked into editing a file located in a maliciously named directory in the repository, then Git GUI can create and overwrite any writable file. https://www.cve.org/CVERecord?id=CVE-2025-46835 - CVE-2025-48384: When reading a config value, Git strips any trailing carriage return and line feed (CRLF). When writing a config entry, values with a trailing CR are not quoted, causing the CR to be lost when the config is later read. When initializing a submodule, if the submodule path contains a trailing CR, the altered path is read resulting in the submodule being checked out to an incorrect location. If a symlink exists that points the altered path to the submodule hooks directory, and the submodule contains an executable post-checkout hook, the script may be unintentionally executed after checkout. https://www.cve.org/CVERecord?id=CVE-2025-48384 - CVE-2025-48385: When cloning a repository Git knows to optionally fetch a bundle advertised by the remote server, which allows the server-side to offload parts of the clone to a CDN. The Git client does not perform sufficient validation of the advertised bundles, which allows the remote side to perform protocol injection. This protocol injection can cause the client to write the fetched bundle to a location controlled by the adversary. The fetched content is fully controlled by the server, which can in the worst case lead to arbitrary code execution. https://www.cve.org/CVERecord?id=CVE-2025-48385 - CVE-2025-48386: The wincred credential helper uses a static buffer (`target`) as a unique key for storing and comparing against internal storage. This credential helper does not properly bounds check the available space remaining in the buffer before appending to it with `wcsncat()`, leading to potential buffer overflows. https://www.cve.org/CVERecord?id=CVE-2025-48386 Signed-off-by: Titouan Christophe <titouan.christophe@mind.be> Signed-off-by: Julien Olivain <ju.o@free.fr>
Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
