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.
