Details
USN-5583-1 fixed vulnerabilities in systemd. Unfortunately this caused a
regression by introducing networking problems for some users. This update fixes
the problem.
We apologize for the inconvenience.
Original advisory details:
It was discovered that systemd incorrectly handled certain DNS requests,
which leads to user-after-free vulnerability. An attacker could possibly use
this issue to cause a crash or execute arbitrary code. (CVE-2022-2526)
