An update that solves 9 vulnerabilities and has two fixes is now available.

Description:

This update for git fixes the following issues:
Security issues fixed:

  o CVE-2019-1349: Fixed issue on Windows, when submodules are cloned
    recursively, under certain circumstances Git could be fooled into using the
    same Git directory twice (bsc#1158787).
  o CVE-2019-19604: Fixed a recursive clone followed by a submodule update
    could execute code contained within the repository without the user
    explicitly having asked for that (bsc#1158795).
  o CVE-2019-1387: Fixed recursive clones that are currently affected by a
    vulnerability that is caused by too-lax validation of submodule names,
    allowing very targeted attacks via remote code execution in recursive
    clones (bsc#1158793).
  o CVE-2019-1354: Fixed issue on Windows that refuses to write tracked files
    with filenames that contain backslashes (bsc#1158792).
  o CVE-2019-1353: Fixed issue when run in the Windows Subsystem for Linux
    while accessing a working directory on a regular Windows drive, none of the
    NTFS protections were active (bsc#1158791).
  o CVE-2019-1352: Fixed issue on Windows was unaware of NTFS Alternate Data
    Streams (bsc#1158790).
  o CVE-2019-1351: Fixed issue on Windows mistakes drive letters outside of the
    US-English alphabet as relative paths (bsc#1158789).
  o CVE-2019-1350: Fixed incorrect quoting of command-line arguments allowed
    remote code execution during a recursive clone in conjunction with SSH URLs
    (bsc#1158788).
  o CVE-2019-1348: Fixed the --export-marks option of fast-import is exposed
    also via the in-stream command feature export-marks=... and it allows
    overwriting arbitrary paths (bsc#1158785).
  o Fixes an issue where git send-email failed to authenticate with SMTP server
    (bsc#1082023)


Bug fixes:

  o Add zlib dependency, which used to be provided by openssl-devel, so that
    package can compile successfully after openssl upgrade to 1.1.1. (bsc#
    1149792).
