CVE-2004-0748
mod_ssl in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (CPU consumption) by aborting an SSL connection in a way that causes an Apache child process to enter an infinite loop.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 24.7%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
