USN-6053-1: PHP vulnerability
2 May 2023
PHP could be made to bypass password checking if a specially crafted input was provided.
Releases
Packages
- php7.0 - HTML-embedded scripting language interpreter
Details
It was discovered that PHP incorrectly handled certain invalid Blowfish
password hashes. An invalid password hash could possibly allow applications to
accept any password as valid, contrary to expectations.

Ubuntu 16.04
