CVE-2019-16254  (opens in a new tab)
CWE-113  (opens in a new tab)

How to fix?

Upgrade Centos:8 ruby-doc to version 0:2.5.9-107.module+el8.4.0+10822+fe4fffb1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby-doc package and not the ruby-doc package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this issue exists because of an incomplete fix for CVE-2017-17742, which addressed the CRLF vector, but did not address an isolated CR or an isolated LF.
