Does this matter?
Lower severity and a low EPSS score (1.65%). Track it; it rarely justifies an emergency change on its own.
Description
A flaw has been identified in glibc. In an uncommon situation, the gaih_inet function may use memory that has been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge.
