CVE-2015-3249 is a vulnerability of currently unknown severity. The HTTP/2 experimental feature in Apache Traffic Server 5.3.x before 5.3.1 allows remote attackers to cause a denial of service (out-of-bounds access and daemon crash) or possibly execute arbitrary code via vectors related to the (1) frame_handlers array or (2) set_dynamic_table_size function.. EPSS estimates a 5.44% chance of exploitation in the next 30 days.
