Title
Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SIP Inspection Denial of Service Vulnerability
Summary
A vulnerability in the Session Initiation Protocol (SIP) inspection module of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper parsing of SIP messages. An attacker could exploit this vulnerability by sending a malicious SIP packet through an affected device. A successful exploit could allow the attacker to trigger an integer underflow, causing the software to try to read unmapped memory and resulting in a crash.

Title
Cisco Integrated Management Controller Denial of Service Vulnerability
Summary
A vulnerability in the web server of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker to cause a buffer overflow, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect bounds checking. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. An exploit could allow the attacker to cause a buffer overflow, resulting in a process crash and DoS condition on the device.
