EulerOS Virtualization for ARM 64 3.0.2.0 : ruby (EulerOS-SA-2019-1617)

critical Nessus Plugin ID 125569

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the ruby packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

 - Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks.Security Fix(es):An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.(CVE-2018-16395)An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats.(CVE-2018-16396)** RESERVED

When the candidate has been publicized, the details for this candidate will be provided.(CVE-2019-8325)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.

Solution

Update the affected ruby packages.
