Doc Text:
A flaw was found in Ruby. When compiling a specially crafted regular expression with the methods Regexp.new, Regexp.union, Regexp.compile, or via a string interpolation such as /#{input}/, an integer overflow in the size of the compiled pattern can occur. This integer overflow causes memory corruption, potentially resulting in arbitrary code execution.

Description OSIDB Bzimport 2026-10-13 01:32:12 UTC
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2 that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server via a specially crafted regular expression in a CI/CD configuration, due to insufficient regular expression validation.
