Cisco fixes serious denial-of-service flaws
Cisco Systems has released patches to fix serious denial-of-service flaws in its Wireless LAN Controller (WLC) software, Cisco Adaptive Security Appliance (ASA) software and the Secure Real-Time Transport Protocol (SRTP) library that's used in many products.
The Cisco WLC software contains two denial-of-service vulnerabilities, one of which is rated critical and could be exploited by an unauthenticated attacker through specially crafted HTTP requests sent to the device. This can cause a buffer overflow condition that, in addition to a device reload, might also allow for execution of arbitrary code on the device.
The second vulnerability, rated high, stems from how the Cisco WLC software handles Bonjour traffic and can be exploited in a similar manner as the HTTP one to cause a device reload.
