Details

It was discovered that Ruby RDoc incorrectly parsed certain YAML files. If
a user or automated system were tricked into parsing a specially crafted
.rdoc_options file, a remote attacker could possibly use this issue to
execute arbitrary code. (CVE-2024-27281)

It was discovered that the Ruby regex compiler incorrectly handled certain
memory operations. A remote attacker could possibly use this issue to
obtain sensitive memory contents. (CVE-2024-27282)
