CVE-2019-16254

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.

Bug Fix(es):

• Resolv::DNS: ruby:2.6/ruby: timeouts if multiple IPv6 name servers are given and address contains leading zero [almalinux-8] (BZ#1954968)

Updated ruby packages fix security vulnerabilities:

It was discovered that Ruby incorrectly handled certain files. An attacker could possibly use this issue to pass path matching what can lead to an unauthorized access (CVE-2019-15845).

It was discovered that Ruby incorrectly handled certain regular expressions. An attacker could use this issue to cause a denial of service (CVE-2019-16201).

It was discovered that Ruby incorrectly handled certain HTTP headers. An attacker could possibly use this issue to execute arbitrary code (CVE-2019-16254).

It was discovered that Ruby incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code (CVE-2019-16255).

Response Splitting attack in the HTTP server of WEBrick (CVE-2017-17742).

Delete directory using symlink when decompressing tar (CVE-2019-8320).

Escape sequence injection vulnerability in verbose (CVE-2019-8321).

Escape sequence injection vulnerability in gem owner (CVE-2019-8322).

Escape sequence injection vulnerability in API response handling (CVE-2019-8323).

Installing a malicious gem may lead to arbitrary code execution (CVE-2019-8324).

Escape sequence injection vulnerability in errors (CVE-2019-8325).

Regular Expression Denial of Service vulnerability of WEBrick's Digest access authentication (CVE-2019-16201).

HTTP Response Splitting attack in the HTTP server of WEBrick (CVE-2019-16254).

Code injection vulnerability (CVE-2019-16255).

A potential HTTP request smuggling vulnerability in WEBrick was reported. WEBrick (bundled along with jruby) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to "smuggle" a request (CVE-2020-25613).
