Synopsis

The remote SUSE host is missing one or more security updates.

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).

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.
