    Git 2.39.1 release notes
    ========================

    This maintenance releass is to address the security issues
    identified as CVE-2022-41903 and CVE-2022-23521.

     * CVE-2022-41903:

       git log has the ability to display commits using an arbitrary
       format with its --format specifiers. This functionality is also
       exposed to git archive via the export-subst gitattribute.

       When processing the padding operators (e.g., %<(, %<|(, %>(,
       %>>(, or %><( ), an integer overflow can occur in
       pretty.c::format_and_pad_commit() where a size_t is improperly
       stored as an int, and then added as an offset to a subsequent
       memcpy() call.

       This overflow can be triggered directly by a user running a
       command which invokes the commit formatting machinery (e.g., git
       log --format=...). It may also be triggered indirectly through
       git archive via the export-subst mechanism, which expands format
       specifiers inside of files within the repository during a git
       archive.

       This integer overflow can result in arbitrary heap writes, which
       may result in remote code execution.

    * CVE-2022-23521:

        gitattributes are a mechanism to allow defining attributes for
        paths. These attributes can be defined by adding a `.gitattributes`
        file to the repository, which contains a set of file patterns and
        the attributes that should be set for paths matching this pattern.

        When parsing gitattributes, multiple integer overflows can occur
        when there is a huge number of path patterns, a huge number of
        attributes for a single pattern, or when the declared attribute
        names are huge.

        These overflows can be triggered via a crafted `.gitattributes` file
        that may be part of the commit history. Git silently splits lines
        longer than 2KB when parsing gitattributes from a file, but not when
        parsing them from the index. Consequentially, the failure mode
        depends on whether the file exists in the working tree, the index or
        both.

        This integer overflow can result in arbitrary heap reads and writes,
        which may result in remote code execution.
