CVE-2015-0646 [HIGH] CWE-399 Cisco IOS Software and IOS XE Software TCP Packet Memory Leak Vulnerability
Cisco IOS Software and IOS XE Software TCP Packet Memory Leak Vulnerability
A vulnerability in the TCP input module of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak and eventual reload of the affected device.
The vulnerability is due to improper handling of certain crafted packet sequences used in establishing a TCP three-way handshake. An attacker could exploit this vulnerability by sending a crafted sequence of TCP packets while establishing a three-way handshake. A successful exploit could allow the attacker to cause a memory leak and eventual reload of the affected device.
There are no workarounds for this vulnerability.
Cisco has released software updates that address this vulnerability. This advisory is available at the
