Snort SID: 36536, 37841-37843. Additional rules pending release of
vulnerability information

Title: Cisco Releases Five Advisories for Various Denial of Service Vulnerabilities
Description: Cisco has released five advisories for various denial of
service vulnerabilities that have been identified in various products.
Four of the five advisories are rated as high-impact while the fifth,
CVE-2016-1363, is rated critical. CVE-2016-1363 manifests due to
improperly handling HTTP URL redirects and could allow an
unauthenticated, remote attacker to trigger the flaw “by sending a
crafted HTTP request to an affected device.” This crafted request could
cause “a buffer overflow condition” to occur and result in a DoS
condition or arbitrary code execution. Cisco has released updated
software that addresses this vulnerability as well as the others.
