Synopsis
The remote device is missing a vendor-supplied security patch.Description
According to its self-reported version, Cisco Secure Client Software, formerly AnyConnect Secure Mobility Client is affected by multiple denial of service (DoS) vulnerabilities. These vulnerabilities are due to an out-of-bounds memory read from Cisco Secure Client Software. An attacker could exploit these vulnerabilities by logging in to an affected device at the same time that another user is accessing Cisco Secure Client on the same system, and then sending crafted packets to a port on that local host. A successful exploit could allow the authenticated attacker to crash the VPN Agent service, causing it to be unavailable to all users of the system. To exploit these vulnerabilities, the attacker must have valid credentials on a multi-user system.Please see the included Cisco BIDs and Cisco Security Advisory for more information.
