Package : php7.4
CVE ID : CVE-2021-21707 CVE-2021-21708

Two security issues were found in PHP, a widely-used open source general
purpose scripting language which could result in information disclosure
or denial of service.

For the stable distribution (bullseye), these problems have been fixed in
version 7.4.28-1+deb11u1.

We recommend that you upgrade your php7.4 packages.

For the detailed security status of php7.4 please refer to
