Vulnerability from variot

A vulnerability in the HostScan component of Cisco AnyConnect Secure Mobility Client for Linux could allow an unauthenticated, remote attacker to read sensitive information on an affected system. The vulnerability exists because the affected software performs improper bounds checks. An attacker could exploit this vulnerability by crafting HTTP traffic for the affected component to download and process. A successful exploit could allow the attacker to read sensitive information on the affected system. This issue is being tracked by Cisco Bug ID CSCvn47574. HostScan is one of the network host scanning components. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations. Attackers can exploit this vulnerability to cause buffer overflow or heap overflow, etc
