RubyGems Security Advisories :

CVE-2019-8320: Delete directory using symlink when decompressing tar

CVE-2019-8321: Escape sequence injection vulnerability in 'verbose'

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.)

For Debian 8 'Jessie', these problems have been fixed in version 2.1.5-2+deb8u7.

We recommend that you upgrade your ruby2.1 packages.
