ap/qpdf-10.0.4-x86_64-1.txz: Upgraded. d/cmake-3.19.1-x86_64-1.txz: Upgraded. n/bind-9.16.9-x86_64-1.txz: Upgraded. This update fixes bugs, including a denial-of-service security issue: After a Negative Trust Anchor (NTA) is added, BIND performs periodic checks to see if it is still necessary. If BIND encountered a failure while creating a query to perform such a check, it attempted to dereference a NULL pointer, resulting in a crash. [GL #2244] (* Security fix *) n/cifs-utils-6.11-x86_64-2.txz: Rebuilt. Patched to fix mounting CIFS shares when linked with libcap-ng-0.8.1. Thanks to marrowsuck.

+Subject: [PATCH 1/2] mount.cifs: update the cap bounding set only when
+ CAP_SETPCAP is given
+
+libcap-ng 0.8.1 tightened the error checking on capng_apply, returning an error
+of -4 when trying to update the capability bounding set without having the
+CAP_SETPCAP capability to be able to do so. Previous versions of libcap-ng
+silently skipped updating the bounding set and only updated the normal
+CAPNG_SELECT_CAPS capabilities instead.
+
+Check beforehand whether we have CAP_SETPCAP, in which case we can use
+CAPNG_SELECT_BOTH to update both the normal capabilities and the bounding set.
+Otherwise, we can at least update the normal capabilities, but refrain from
+trying to update the bounding set to avoid getting an error.
