Fixes a potential security issue. - do not follow symlinks that are the final path element (CVE-2020-8013, bsc#1163922) - fix handling of relative directory symlinks in chkstat - whitelist postgres sticky directories (bsc#1123886) - fix regression where chkstat breaks without /proc available (bsc#1160764, bsc#1160594) - fix capability handling when doing multiple permission changes at once (bsc#1161779, - fix invalid free() when permfiles points to argv (bsc#1157198) - the eror should be reported for permfiles[i], not argv[i], as these are not the same files. (bsc#1047247, bsc#1097665) - fix /usr/sbin/pinger ownership to root:squid (bsc#1093414, CVE-2019-3688) - fix privilege escalation through untrusted symlinks (bsc#1150734, CVE-2019-3690) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
