    CVE ID         : CVE-2024-53263
    Debian Bug     : 1093048

    CVE-2024-53263

        When Git LFS requests credentials from Git for a remote host, it
        passes portions of the host's URL to the `git-credential(1)` command
        without checking for embedded line-ending control characters, and then
        sends any credentials it receives back from the Git credential helper
        to the remote host. By inserting URL-encoded control characters such
        as line feed (LF) or carriage return (CR) characters into the URL,
        an attacker may be able to retrieve a user's Git credentials.

    For Debian 11 bullseye, this problem has been fixed in version
    2.13.2-1+deb11u1.

    We recommend that you upgrade your git-lfs packages.
