    Package        : phpseclib     Version        : 1.0.19-3+deb11u3     CVE ID         : CVE-2023-52892 CVE-2026-32935

    Two vulnerabilities were discovered in phpseclib, a PHP Secure     Communications Library.

    CVE-2023-52892

        Some characters in Subject Alternative Name fields in TLS         certificates were incorrectly allowed to have a special meaning         in regular expressions, leading to name confusion in X.509         certificate host verification.

    CVE-2026-32935

        The AES-CBC implementation was susceptible to a padding oracle         timing attack due to the use of a short-circuiting logical         operator in the unpadding function.

    For Debian 11 bullseye, these problems have been fixed in version     1.0.19-3+deb11u3.

    We recommend that you upgrade your phpseclib packages.
