   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.
