Symantec pcAnywhere Multiple Vulnerabilities (SYM12-002)

This script is Copyright (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

An application installed on the remote host is affected by multiple
remote vulnerabilities.

Description :

The version of Symantec pcAnywhere installed on the remote host is
potentially affected by multiple vulnerabilities :

- When handling an authentication request the process
copies the user-supplied username unsafely to a
fixed-length buffer, which could lead to arbitrary code
execution. (CVE-2011-3478)

- A local privilege escalation vulnerability exists
because some files uploaded to the system during
product installation are installed as writable by
everyone. (CVE-2011-3479)

- During a valid client server session unexpected input to
the client can result in an exception error. This can
create an acess violation resulting in the remote
session being dropped but leaving the client session
open in specific instances. (CVE-2012-0290)

- Malformed input to a client or server or, an unexpected
response to a request could potentially destabilize the
application causing it to hang or crash resulting in a
denial of service. (CVE-2012-0291)
