regex vulnerabilities

This tag page tracks regex vulnerabilities involving regular-expression processing, with the available discussion centered on CVE-2026-8376 in Perl. The issue affects Perl versions through 5.43.10 and can cause a heap buffer overflow in 32-bit builds when compiling expressions that repeat a fixed string. The risk is especially relevant to Windows administrators because Perl may be embedded in older or less visible tooling stacks, even when the underlying operating system is not the source of the flaw. Coverage emphasizes practical security maintenance: inventorying language runtimes, recognizing legacy 32-bit components, and reviewing applicable Microsoft Security Update Guide information rather than treating the vulnerability as a broad Windows defect.
