Notes

Title of the patch
Security update for permissions
Description of the patch
This update for permissions fixes the following issues: Security issues fixed: - CVE-2019-3687: Fixed a privilege escalation which could 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).
