3. Description:

The http-parser package provides a utility for parsing HTTP messages. It
parses both requests and responses. The parser is designed to be used in
performance HTTP applications. It does not make any system calls or
allocations, it does not buffer data, and it can be interrupted at any
time. Depending on your architecture, it only requires about 40 bytes of
data per message stream.

Security Fix(es):

* nodejs: Denial of Service with large HTTP headers (CVE-2018-12121)

* nodejs: HTTP parser allowed for spaces inside Content-Length header
values (CVE-2018-7159)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
