"This update for git fixes the following issues :

Security issues fixed :

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).

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).

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).

CVE-2019-1354: Fixed issue on Windows that refuses to write tracked
files with filenames that contain backslashes (bsc#1158792).

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).

CVE-2019-1352: Fixed issue on Windows was unaware of NTFS Alternate
Data Streams (bsc#1158790).

CVE-2019-1351: Fixed issue on Windows mistakes drive letters outside
of the US-English alphabet as relative paths (bsc#1158789).

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).

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).

Fixed an issue where git send-email fails to authenticate with SMTP
server (bsc#1082023)

description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
