Symantec pcAnywhere Multiple Vulnerabilities (SYM12-002)

critical Nessus Plugin ID 57796


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


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)
