CVE-2007-1306
Asterisk 1.4 before 1.4.1 and 1.2 before 1.2.16 allows remote attackers to cause a denial of service (crash) by sending a Session Initiation Protocol (SIP) packet without a URI and SIP-version header, which results in a NULL pointer dereference.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 20.9%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
