    Debian Bug     : 1091383


    Multiple vulnerabilities have been discovered in Pagure, a Git-centered
    code hosting system (forge).


    CVE-2024-4981

       The function _update_file_in_git() follows symbolic links in
       temporary clones. The fix is to bail out if a file path is outside
       the temp repo or inside the '.git/' folder to avoid data leak and
       unauthorized changes in files or git config.

    CVE-2024-4982

       Path traversal in view_issue_raw_file().

    CVE-2024-47515

       The generate_archive() function follows symbolic links in temporary
       clones. The fix is to the add actual link rather than the target
       content to the zip archive.

    CVE-2024-47516

       Fix an injection of additional options to the Git command-line
       during retrieval of the repository history to prevent remote code
       execution.


    For Debian 11 bullseye, these problems have been fixed in version
    5.11.3+dfsg-1+deb11u1.

    We recommend that you upgrade your pagure packages.
