### Impact The REXML gem before 3.2.6 has a DoS vulnerability when it parses an XML that has many `<`s in an attribute value. If you need to parse untrusted XMLs, you many be impacted to this vulnerability. ### Patches The REXML gem 3.2.7 or later include the patch to fix this vulnerability. ### Workarounds Don't parse untrusted XMLs. ### References * https://www.ruby-lang.org/en/news/2024/05/16/dos-rexml-cve-2024-35176/

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. We recommend to update the RDoc gem to version 6.6.3.1 or later. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead: * For Ruby 3.0 users: Update to `rdoc` 6.3.4.1 * For Ruby 3.1 users: Update to `rdoc` 6.4.1.1 * For Ruby 3.2 users: Update to `rdoc` 6.5.1.1 You can use `gem update rdoc` to update it. If you are using bundler, please add `gem "rdoc", ">= 6.6.3.1"` to your `Gemfile`. Note: 6.3.4, 6.4.1, 6.5.1 and 6.6.3 have a incorrect fix. We recommend to upgrade 6.3.4.1, 6.4.1.1, ...
An 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. This vulnerability is not affected StringIO 3.0.3 and later, and Ruby 3.2.x and later. We recommend to update the StringIO gem to version 3.0.3 or later. In order to ensure compatibility with bundled version in older Ruby series, you may update as follows instead: * For Ruby 3.0 users: Update to `stringio` 3.0.1.1 * For Ruby 3.1 users: Update to `stringio` 3.1.0.2 You can use `gem update stringio` to update it. If you are using bundler, please add `gem "stringio", ">= 3.0.1.2"` to your `Gemfile`.
