Red Hat update for http-parser

1) HTTP response splitting

EUVDB-ID: #VU12575

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-7159

CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to write arbitrary files on the target system.

The weakness exists due to spaces in Content-Length HTTP headers from Node.js’s HTTP module entirely ignore spaces within the value, despite the HTTP specification not allowing spaces within the values. A remote attacker can confuse the script and write arbitrary files.

Mitigation

Install updates from vendor's website.

2) Heap-based buffer overflow

EUVDB-ID: #VU16168

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-12121

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to heap-based buffer overflow. A remote attacker can send many requests with the maximum size HTTP header of nearly 80kb/connection in combination with carefully handled completion of those headers, trigger memory corruption and cause the Node.js HTTP server to abort.

Mitigation

Install updates from vendor's website.
