CVE-2019-16254  (opens in a new tab)
CWE-74  (opens in a new tab)

How to fix?

Upgrade SLES:15.1 ruby2.5-stdlib to version 2.5.7-4.8.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby2.5-stdlib package and not the ruby2.5-stdlib package as distributed by SLES. See How to fix? for SLES:15.1 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.
