Package : php7.3
CVE ID : CVE-2021-21704 CVE-2021-21705
Multiple security issues were found in PHP, a widely-used open source
general purpose scripting language which could result an SSRF bypass
of the FILTER_VALIDATE_URL check and denial of service or potentially
the execution of arbitrary code in the Firebird PDO.
For the stable distribution (buster), these problems have been fixed in
version 7.3.29-1~deb10u1.
We recommend that you upgrade your php7.3 packages.
For the detailed security status of php7.3 please refer to
its security tracker page at:
