Alpine: ruby: security update to 2.5.5-r0

high Tenable Cloud Security Plugin ID 406978

Description

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

- A Directory Traversal issue was discovered in RubyGems 2.7.6 and later through 3.0.2. Before making new
directories or touching files (which now include path-checking code for symlinks), it would delete the
target destination. If that destination was hidden behind a symlink, a malicious gem could delete
arbitrary files on the user's machine, presuming the attacker could guess at paths. Given how frequently
gem is run as sudo, and how predictable paths are on modern systems (/tmp, /usr, etc.), this could likely
lead to data loss or an unusable system. (CVE-2019-8320)

- An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::UserInteraction#verbose calls
say without escaping, escape sequence injection is possible. (CVE-2019-8321)

- An issue was discovered in RubyGems 2.6 and later through 3.0.2. The gem owner command outputs the
contents of the API response directly to stdout. Therefore, if the response is crafted, escape sequence
injection may occur. (CVE-2019-8322)

- An issue was discovered in RubyGems 2.6 and later through 3.0.2. Gem::GemcutterUtilities#with_response may
output the API response to stdout as it is. Therefore, if the API side modifies the response, escape
sequence injection may occur. (CVE-2019-8323)
