Debian DLA-2007-1 : ruby2.1 security update

Description

Several flaws have been found in ruby2.1, an interpreter of an object-oriented scripting language. CVE-2019-15845 Path matching might pass in File.fnmatch and File.fnmatch? due to a NUL character injection. CVE-2019-16201 A loop caused by a wrong regular expression could lead to a denial of service of a WEBrick service. CVE-2019-16254 This is the same issue as CVE-2017-17742, whose fix was not complete. CVE-2019-16255 Giving untrusted data to the first argument of Shell#[] and Shell#test might lead to a code injection vulnerability. For Debian 8 'Jessie', these problems have been fixed in version 2.1.5-2+deb8u8. We recommend that you upgrade your ruby2.1 packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
