sd-bus: enforce a size limit on D-Bus object paths
Replace stack with heap allocation. This avoids accessing/modifying
memory outside of the allocated stack region by sending specially
crafted D-Bus messages with very large object paths.
Vulnerability discovered by Chris Coulson <chris.coulson@canonical.com>,
patch provided by Riccardo Schirone <rschiron@redhat.com>.
CVE-2019-6454
Gbp-Pq: Name sd-bus-enforce-a-size-limit-on-D-Bus-object-paths.patch

systemd (241-7~deb10u4) buster; urgency=medium
* polkit: when authorizing via PolicyKit re-resolve callback/userdata
instead of caching it.
This fixes a heap use-after-free vulnerability in systemd, when
asynchronous PolicyKit queries are performed while handling DBus messages.
CVE-2020-1712 (Closes: #950732)
* Install 60-block.rules in udev-udeb and initramfs-tools.
The block device rules were split out from 60-persistent-storage.rules
into its own rules file in v220. Those rules ensure that change events
are emitted and the udev db is updated after metadata changes.
