CVE-2014-0244
The sys_recvfrom function in nmbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a malformed UDP packet.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 20.5%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
