CVE-2011-3272
The IP Service Level Agreement (IP SLA) functionality in Cisco IOS 15.1, and IOS XE 2.1.x through 3.3.x, allows remote attackers to cause a denial of service (memory corruption and device reload) via malformed IP SLA packets, aka Bug ID CSCtk67073.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.56%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
