"This update for osc to version 0.165.4 fixes the following issues :

Security issue fixed :

  - CVE-2019-3685: Fixed broken TLS certificate handling
    allowing for a Man-in-the-middle attack (bsc#1142518).

Non-security issues fixed :

  - support different token operations (runservice, release
    and rebuild) (requires OBS 2.10)

  - fix osc token decode error

  - offline build mode is now really offline and does not
    try to download the buildconfig

  - osc build -define now works with python3

  - fixes an issue where the error message on osc meta -e
    was not parsed correctly

  - osc maintainer -s now works with python3

  - simplified and fixed osc meta -e (bsc#1138977) 

  - osc lbl now works with non utf8 encoding (bsc#1129889)

  - add simpleimage as local build type 

  - allow optional fork when creating a maintenance request

  - fix RPMError fallback

  - fix local caching for all package formats

  - fix appname for trusted cert store

  - osc -h does not break anymore when using plugins 

  - switch to difflib.diff_bytes and sys.stdout.buffer.write
    for diffing. This will fix all decoding issues with osc
    diff, osc ci and osc rq -d

  - fix osc ls -lb handling empty size and mtime

  - removed decoding on osc api command.

This update was imported from the SUSE:SLE-15-SP1:Update update
