VanDyke Software SecureCRT < 8.7.2 Memory Corruption

critical Nessus Plugin ID 138818

Language:

Synopsis

A terminal emulation application installed on the remote Linux host is affected by a memory corruption vulnerability.

Description

The version of VanDyke Software SecureCRT installed on the remote Linux host is prior to 8.7.2. It is, therefore, affected by a memory corruption vulnerability. An unauthenticated remote attacker may be able to exploit this vulnerability, via a malformed response, to corrupt memory in the terminal process and execute arbitrary code.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to VanDyke Software SecureCRT 8.7.2 or later.
