CVE-2018-25103
There exists use-after-free vulnerabilities in lighttpd <= 1.4.50 request parsing which might read from invalid pointers to memory used in the same request, not from other requests.
Does this matter?
Lower severity and a low EPSS score (0.67%). Track it; it rarely justifies an emergency change on its own.
