Affected versions of charset
are susceptible to a regular expression denial of service.
The amplification on this vulnerability is relatively low - it takes around 2 seconds for the engine to execute on a malicious input which is 50,000 characters in length.
If node was compiled using the -DHTTP_MAX_HEADER_SIZE
however, the impact of the vulnerability can be significant, as the primary limitation for the vulnerability is the default max HTTP header length in node.
Update to version 1.0.1 or later.
