Description

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).

  • Fixes an issue where git send-email failed to authenticate with SMTP server (bsc#1082023)

Bug fixes :

  • 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).

This update was imported from the SUSE:SLE-15:Update update project.
