 Package : php7.4 Version : 7.4.33-1+deb11u10 CVE ID : CVE-2025-14178 Debian Bug : 1123574

 Multiple security issues were found in PHP, a widely-used open source general purpose scripting language, which could result in server side request forgery or denial of service.

 CVE-2025-14178

 Heap buffer overflow in array_merge().

 GHSA-www2-q4fc-65wf

 dns_get_record() and other DNS functions don't have any null contain check, which may lead to SSRF or unexpected behavior. While this has a (low) security impact, no CVE ID was assigned for this vulnerability yet.

 For Debian 11 bullseye, these problems have been fixed in version 7.4.33-1+deb11u10.

 We recommend that you upgrade your php7.4 packages.
