Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The Update method in src/node_http_parser.cc in Node.js before 0.6.17 and 0.7 before 0.7.8 does not properly check the length of a string, which allows remote attackers to obtain sensitive information (request header contents) and possibly spoof HTTP headers via a zero length string.

Mitigation

Install update from vendor's website.
