Security issues fixed :

    allow a local user to read network traffic if wireshark
    is installed (bsc#1148788)

  - CVE-2020-8013: Fixed an issue where chkstat set
    unintended setuid/capabilities for mrsh and wodim
    (bsc#1163922).

Non-security issues fixed :

  - Fixed a regression where chkstat breaks without /proc
    available (bsc#1160764, bsc#1160594).

  - Fixed capability handling when doing multiple permission
    changes at once (bsc#1161779).

Security issue fixed :

CVE-2020-8013: Fixed a local privilege escalation with mrsh and wodim
(bsc#1163922).

Non-security issues fixed :

Fixed regression where chkstat breaks without /proc available
(bsc#1160764, bsc#1160594)

Fixed capability handling when doing multiple permission changes at
once (bsc#1161779)

Fixed handling of relative directory symlinks in chkstat

Note that Tenable Network Security has extracted the preceding
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."
