Alpine: ruby2.2: security update to 2.2.8-r0

critical Tenable Cloud Security Plugin ID 407011

Description

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

- The Basic authentication code in WEBrick library in Ruby before 2.2.8, 2.3.x before 2.3.5, and 2.4.x
through 2.4.1 allows remote attackers to inject terminal emulator escape sequences into its log and
possibly execute arbitrary commands via a crafted user name. (CVE-2017-10784)

- Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious
specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap
memory corruption or an information disclosure from the heap. (CVE-2017-0898)

- RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications that include
terminal escape characters. Printing the gem specification would execute terminal escape sequences.
(CVE-2017-0899)

- RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications to cause a
denial of service attack against RubyGems clients who have issued a `query` command. (CVE-2017-0900)

- RubyGems version 2.6.12 and earlier fails to validate specification names, allowing a maliciously crafted
gem to potentially overwrite any file on the filesystem. (CVE-2017-0901)
