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).
