Alpine: multiple ruby packages: security update to 2.6.5-r0

high Tenable Cloud Security Plugin ID 424457

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within
File.fnmatch functions. (CVE-2019-15845)

- WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a
regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server
that uses DigestAuth to the Internet or a untrusted network. (CVE-2019-16201)

- 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. (CVE-2019-16254)

- Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first
argument (aka the "command" argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An
attacker can exploit this to call an arbitrary Ruby method. (CVE-2019-16255)
