Synopsis
The remote Red Hat host is missing one or more security updates for ruby.Description
The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1912 advisory.Ruby is an extensible, interpreted, object-oriented, scripting language.
It has features to process text files and to perform system management tasks.
Multiple denial of service flaws were found in the way the Ruby REXML XML parser performed expansion of parameter entities. A specially crafted XML document could cause REXML to use an excessive amount of CPU and memory.
(CVE-2014-8080, CVE-2014-8090)
A stack-based buffer overflow was found in the implementation of the Ruby Array pack() method. When performing base64 encoding, a single byte could be written past the end of the buffer, possibly causing Ruby to crash.
(CVE-2014-4975)
The CVE-2014-8090 issue was discovered by Red Hat Product Security.
All ruby users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of Ruby need to be restarted for this update to take effect.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL ruby package based on the guidance in RHSA-2014:1912.See Also
