EulerOS 2.0 SP1 : ruby (EulerOS-SA-2017-1050)
High Nessus Plugin ID 99895
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- An exploitable heap overflow vulnerability exists in the Fiddle::Function.new 'initialize' function functionality of Ruby. In Fiddle::Function.new 'initialize' heap buffer 'arg_types' allocation is made based on args array length. Specially constructed object passed as element of args array can increase this array size after mentioned allocation and cause heap overflow.(CVE-2016-2339)
- Type confusion exists in _cancel_eval Ruby's TclTkIp class method. Attacker passing different type of object than String as 'retval' argument can cause arbitrary code execution.(CVE-2016-2337)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected ruby packages.
