Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 29.1%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.

Description

Buffer overflow in htdigest in Apache 2.0.52 may allow attackers to execute arbitrary code via a long realm argument. NOTE: since htdigest is normally only locally accessible and not setuid or setgid, there are few attack vectors which would lead to an escalation of privileges, unless htdigest is executed from a CGI program. Therefore this may not be a vulnerability.
