libgit2: Update to 0.28.4


This is a security release fixing the following issues:

- CVE-2019-1348: the fast-import stream command "feature
  export-marks=path" allows writing to arbitrary file paths. As
  libgit2 does not offer any interface for fast-import, it is not
  susceptible to this vulnerability.

- CVE-2019-1349: by using NTFS 8.3 short names, backslashes or
  alternate filesystreams, it is possible to cause submodules to
  be written into pre-existing directories during a recursive
  clone using git. As libgit2 rejects cloning into non-empty
  directories by default, it is not susceptible to this

- CVE-2019-1350: recursive clones may lead to arbitrary remote
  code executing due to improper quoting of command line
  arguments. As libgit2 uses libssh2, which does not require us
  to perform command line parsing, it is not susceptible to this

- CVE-2019-1351: Windows provides the ability to substitute
  drive letters with arbitrary letters, including multi-byte
  Unicode letters. To fix any potential issues arising from
  interpreting such paths as relative paths, we have extended
  detection of DOS drive prefixes to accomodate for such cases.

- CVE-2019-1352: by using NTFS-style alternative file streams for
  the ".git" directory, it is possible to overwrite parts of the
  repository. While this has been fixed in the past for Windows,
  the same vulnerability may also exist on other systems that
  write to NTFS filesystems. We now reject any paths starting
  with ".git:" on all systems.

- CVE-2019-1353: by using NTFS-style 8.3 short names, it was
  possible to write to the ".git" directory and thus overwrite
  parts of the repository, leading to possible remote code
  execution. While this problem was already fixed in the past for
  Windows, other systems accessing NTFS filesystems are
  vulnerable to this issue too. We now enable NTFS protecions by
  default on all systems to fix this attack vector.

- CVE-2019-1354: on Windows, backslashes are not a valid part of
  a filename but are instead interpreted as directory separators.
  As other platforms allowed to use such paths, it was possible
  to write such invalid entries into a Git repository and was
  thus an attack vector to write into the ".git" dierctory. We
  now reject any entries starting with ".git\" on all systems.

- CVE-2019-1387: it is possible to let a submodule's git
  directory point into a sibling's submodule directory, which may
  result in overwriting parts of the Git repository and thus lead
  to arbitrary command execution. As libgit2 doesn't provide any
  way to do submodule clones natively, it is not susceptible to
  this vulnerability. Users of libgit2 that have implemented
  recursive submodule clones manually are encouraged to review
  their implementation for this vulnerability.
