Affected packages

• Packagist phpseclib/phpseclib: < 1.0.22 → fixed in 1.0.22 • Packagist phpseclib/phpseclib: >= 2.0.0, < 2.0.46 → fixed in 2.0.46 • Packagist phpseclib/phpseclib: >= 3.0.0, < 3.0.33 → fixed in 3.0.33

Description

In phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification.
