MiracleLinux 8 : ruby:3.1 (AXSA:2024-8503:01)
critical Nessus Plugin ID 293281
Synopsis
The remote MiracleLinux host is missing one or more security updates.Description
The remote MiracleLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2024-8503:01 advisory.* ruby: RCE vulnerability with .rdoc_options in RDoc (CVE-2024-27281)
* ruby: Buffer overread vulnerability in StringIO (CVE-2024-27280)
* ruby: Arbitrary memory address read vulnerability with Regex search (CVE-2024-27282) CVE-2024-27280 A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and 3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however, for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is stringio 3.0.1.2.
CVE-2024-27281 An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby 3.x through 3.3.0. When parsing .rdoc_options (used for configuration in RDoc) as a YAML file, object injection and resultant remote code execution are possible because there are no restrictions on the classes that can be restored.
(When loading the documentation cache, object injection and resultant remote code execution are also possible if there were a crafted cache.) The main fixed version is 6.6.3.1. For Ruby 3.0 users, a fixed version is rdoc 6.3.4.1. For Ruby 3.1 users, a fixed version is rdoc 6.4.1.1. For Ruby 3.2 users, a fixed version is rdoc 6.5.1.1.
CVE-2024-27282 An issue was discovered in Ruby 3.x through 3.3.0. If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings. The fixed versions are 3.0.7, 3.1.5, 3.2.4, and 3.3.1.
