"This update for libzypp, zypper fixes the following issues :

Update zypper to version 1.14.41

Update libzypp to 17.25.4

  - CVE-2017-9271: Fixed information leak in the log file
    (bsc#1050625 bsc#1177583)

  - RepoManager: Force refresh if repo url has changed
    (bsc#1174016)

  - RepoManager: Carefully tidy up the caches. Remove
    non-directory entries. (bsc#1178966)

  - RepoInfo: ignore legacy type= in a .repo file and let
    RepoManager probe (bsc#1177427).

  - RpmDb: If no database exists use the _dbpath configured
    in rpm. Still makes sure a compat symlink at
    /var/lib/rpm exists in case the configures _dbpath is
    elsewhere. (bsc#1178910)

  - Fixed update of gpg keys with elongated expire date
    (bsc#179222)

  - needreboot: remove udev from the list (bsc#1179083)

  - Fix lsof monitoring (bsc#1179909)

yast-installation was updated to 4.2.48 :

  - Do not cleanup the libzypp cache when the system has low
    memory, incomplete cache confuses libzypp later
    (bsc#1179415)

This update was imported from the SUSE:SLE-15-SP2:Update update
