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

Update zypper to version 1.14.43 :

doc: give more details about creating versioned package locks
(bsc#1181622)

man: Document synonymously used patch categories (bsc#1179847)

Fix source-download commands help (bsc#1180663)

man: Recommend to use the --non-interactive global option rather than
the command option -y (bsc#1179816)

Extend apt packagemap (fixes #366)

--quiet: Fix install summary to write nothing if there's nothing todo
(bsc#1180077)

Prefer /run over /var/run.

Update libzypp to 17.25.8 :

Try to provide a mounted /proc in --root installs (bsc#1181328) Some
systemd tools require /proc to be mounted and fail if it's not there.

Enable release packages to request a releaxed suse/opensuse
vendorcheck in dup when migrating. (bsc#1182629)

Patch: Identify well-known category names (bsc#1179847) This allows to
use the RH and SUSE patch categrory names synonymously: (recommended =
bugfix) and (optional = feature = enhancement).

Add missing includes for GCC 11 compatibility.

Fix %posttrans script execution (fixes #265) The scripts are
execuable. No need to call them through 'sh -c'.

Commit: Fix rpmdb compat symlink in case rpm got removed.

Repo: Allow multiple baseurls specified on one line (fixes #285)

Regex: Fix memory leak and undefined behavior.

Add rpm buildrequires for test suite (fixes #279)

Use rpmdb2solv new -D switch to tell the location ob the rpmdatabase
to use.

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#1179222)

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

Fix lsof monitoring (bsc#1179909)

Rephrase solver problem descriptions (jsc#SLE-8482)

Adapt to changed gpg2/libgpgme behavior (bsc#1180721)

Multicurl backend breaks with with unknown filesize (fixes #277)

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.");
