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~deb10u3) buster; urgency=medium
* core: set fs.file-max sysctl to LONG_MAX rather than ULONG_MAX.
Since kernel 5.2 (but also stable kernels like 4.19.53) the kernel
thankfully returns proper errors when we write a value out of range to
the sysctl. Which however breaks writing ULONG_MAX to request the
maximum value. Hence let's write the new maximum value instead,
LONG_MAX. (Closes: #945018)
* core: change ownership/mode of the execution directories also for static
users.
This ensures that execution directories like CacheDirectory and
StateDirectory are properly chowned to the user specified in User= before
launching the service. (Closes: #919231)
