Multiple security issues were found in PHP, a widely-used open source
general purpose scripting language which could result in denial of
service, SQL injection, cross-site scripting, information disclosure
or the execution of arbitrary code.
For the stable distribution (trixie), these problems have been fixed in
version 8.4.21-1~deb13u1.
We recommend that you upgrade your php8.4 packages.
