QID 750030: SUSE Enterprise Linux Security Update for xen (SUSE-SU-2021:1648-1)

This update for xen fixes the following issues: security issue fixed: - cve-2021-28689: fixed some x86 speculative vulnerabilities with bare (non-shim) 32-bit pv guests (xsa-370) (bsc#1185104) - make sure xencommons is in a format as expected by fillup. (
Bsc#1185682) each comment needs to be followed by an enabled key.
Otherwise fillup will remove manually enabled key=value pairs, along with everything that looks like a stale comment, during next pkg update - a recent systemd update caused a regression in xenstored.service systemd now fails to track units that use systemd-notify (bsc#1183790) - added a delay between the call to systemd-notify and the final exit of the wrapper script (bsc#1185021, bsc#1185196)

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

Successful exploitation allows attacker to compromise the system.
