HIGH 7.5REMOTEUPGRADE

CVE-2014-10064 is a high-severity flaw (CVSS 7.5) affecting qs. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The qs module before 1.0.0 does not have an option or default for specifying object depth and when parsing a string representing a deeply nested object will block the event loop for long periods of time. An attacker could leverage this to cause a temporary denial-of-service condition, for example, in a web application, other requests would not be processed while this blocking is occurring.

Why this priority

High severity
Remotely exploitable, no login, no user action

A fixed release or distro patch exists.
