RHEL 7 : http-parser (RHSA-2019:2258)

medium Nessus Plugin ID 127700

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for http-parser.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2258 advisory.

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)

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

Solution

Update the RHEL http-parser package based on the guidance in RHSA-2019:2258.
