Summary
The remote host is missing an update for the 'ruby2.1' package(s) announced via the DSA-1735-1 advisory.
Insight
Insight
Several vulnerabilities have been discovered in rubygems embedded in ruby2.1, the interpreted scripting language. CVE-2019-8320 A Directory Traversal issue was discovered in RubyGems. Before making new directories or touching files (which now include path-checking code for symlinks), it would delete the target destination. CVE-2019-8322 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-2019-8323 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-2019-8324 A crafted gem with a multi-line name is not handled correctly. Therefore, an attacker could inject arbitrary code to the stub line of gemspec, which is eval-ed by code in ensure_loadable_spec during the preinstall check. CVE-2019-8325 An issue was discovered in RubyGems 2.6 and later through 3.0.2. Since Gem::CommandManager#run calls alert_error without escaping, escape sequence injection is possible. (There are many ways to cause an error.)
