Title:	Debian: Security Advisory (DLA-1735-1)
Summary:	The remote host is missing an update for the Debian 'ruby2.1' package(s) announced via the DLA-1735-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'ruby2.1' package(s) announced via the DLA-1735-1 advisory. Vulnerability 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.) 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.

Solution: Please install the updated package(s). CVSS Score: 8.8 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:C/A:C
