Amazon Linux 2 : ruby (ALAS-2019-1143)
High Nessus Plugin ID 121052
SynopsisThe remote Amazon Linux 2 host is missing a security update.
DescriptionAn issue was discovered in the OpenSSL library in Ruby. 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)
SolutionRun 'yum update ruby' to update your system.
