Title:	Cisco WSA Multiple Vulnerabilities 05/16
Summary:	Cisco WSA Software is prone to multiple vulnerabilities. CVE-2016-1380 A vulnerability that occurs when parsing an HTTP POST request with Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) vulnerability due to the proxy process becoming unresponsive. CVE-2016-1381 A vulnerability in the cached file-range request functionality of Cisco AsyncOS for Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an appliance due to the appliance running out of system memory. CVE-2016-1382 A vulnerability in HTTP request parsing in Cisco AsyncOS for the Cisco Web Security Appliance (WSA) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition when the proxy process unexpectedly restarts. CVE-2016-1383 A vulnerability in Cisco AsyncOS for the Cisco Web Security Appliance (WSA) when the software handles a specific HTTP response code could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an appliance because the appliance runs out of system memory.
