Details

It was discovered that phpseclib, a pure-PHP implementation of various cryptographic and arithmetic algorithms (v1), mishandles RSA PKCS#1 v1.5 signature verification. An attacker may get invalid signatures accepted, bypassing authorization control in specific situations.

For Debian 10 buster, this problem has been fixed in version 1.0.19-3~deb10u1.

We recommend that you upgrade your phpseclib packages.

For the detailed security status of phpseclib please refer to its security tracker page at: https://security-tracker.debian.org/tracker/phpseclib
