Debian published security advisories DSA-6185-1 and DSA-6187-1 for the phpseclib and php-phpseclib3 packages, issuing fixes for vulnerabilities in the PHP cryptography libraries. The updates affect both the legacy phpseclib package line and the newer php-phpseclib3 package, indicating that multiple supported branches required remediation.
The advisories provide patched Debian packages through the distribution's security channels so administrators can update affected systems running applications that depend on these libraries. Organizations using PHP-based encryption, SSH, or key-handling functionality through phpseclib should review package exposure and apply the Debian security updates promptly to reduce the risk from flaws in these widely used components.
