        "text": "Multiple vulnerabilities in Cisco Secure Client Software, formerly AnyConnect Secure Mobility Client, could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system.\r\n\r\nThese 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 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.\r\n\r\nCisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.\r\n\r\n\r\n\r\nAttention: Simplifying the Cisco portfolio includes the renaming of security products under one brand: Cisco Secure.
