Cisco Firepower Detection Engine SSL Denial of Service Vulnerability

A vulnerability in the detection engine that handles Secure Sockets Layer SSL packets for Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause a denial of service DoS condition because the Snort process unexpectedly restarts. SPDX-FileCopyrightText: 2017...

CVE-2017-6658

Cisco Sourcefire Snort 3.0 before build 233 has a Buffer Overread related to use of a decoder array. The size was off by one making it possible to read past the end of the array with an ether type of 0xFFFF. Increasing the array size solves this problem...

CVE-2017-6657

Cisco Sourcefire Snort 3.0 before build 233 mishandles Ether Type Validation. Since valid ether type and IP protocol numbers do not overlap, Snort++ stores all protocol decoders in a single array. That makes it possible to craft packets that have IP protocol numbers in the ether type field which...

CVE-2017-6657

Cisco Sourcefire Snort 3.0 before build 233 mishandles Ether Type Validation, allowing crafted packets with IP protocol numbers in the ether type field to confuse the Snort++ decoder. Affected decoders include gre, llc, trans_bridge, ciscometadata, linux_sll, and token_ring; the fix adds a check ...

CVE-2017-6658

CVE-2017-6658 affects Cisco Sourcefire Snort 3.0 prior to build 233, with a buffer overread in the decoder array caused by an off-by-one sizing error. An ether type of 0xFFFF could lead to reading past the end of the array, with the recommended mitigation being to increase the decoder array size ...
