Alpine: ruby: security update to 3.1.5-r0

critical Tenable Self-Hosted Container Security Plugin ID 408382

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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-2024-27280)

- 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-2024-27281)

- 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. (CVE-2024-27282)
