Summary
Cisco AnyConnect Secure Mobility Client for Linux Out-of-Bounds Memory Read Vulnerability
Notes
Summary
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.
There are no workarounds that address this vulnerability.
