Alpine: multiple ruby packages: security update to 2.5.2-r0
critical Tenable Self-Hosted Container Security Plugin ID 424426
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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
