    Package        : libgit2     Version        : 0.27.7+dfsg.1-0.2+deb10u1     CVE ID         : CVE-2020-12278 CVE-2020-12279 CVE-2023-22742     Debian Bug     : 1029368

    A vulnerability have been found in libgit2, a cross-platform, linkable     library implementation of Git, which may result in remote code execution     when cloning a repository on a NTFS-like filesystem or man-in-the-middle     attacks due to improper verification of cryptographic Signature.

    CVE-2020-12278

        An issue was discovered in libgit2 before 0.28.4 and 0.9x before         0.99.0.  path.c mishandles equivalent filenames that exist because of         NTFS Alternate Data Streams. This may allow remote code execution when         cloning a repository.

    CVE-2020-12279

        An issue was discovered in libgit2 before 0.28.4 and 0.9x before         0.99.0.  checkout.c mishandles equivalent filenames that exist because         of NTFS short names. This may allow remote code execution when cloning a         repository

    CVE-2023-22742

        libgit2 is a cross-platform, linkable library implementation of Git.
        When using an SSH remote with the optional libssh2 backend, libgit2 does         not perform certificate checking by default. Prior versions of libgit2         require the caller to set the `certificate_check` field of libgit2's         `git_remote_callbacks` structure - if a certificate check callback is         not set, libgit2 does not perform any certificate checking. This means         that by default - without configuring a certificate check callback,         clients will not perform validation on the server SSH keys and may be         subject to a man-in-the-middle attack.

    For Debian 10 buster, these problems have been fixed in version     0.27.7+dfsg.1-0.2+deb10u1.

    We recommend that you upgrade your libgit2 packages.
