USN-8564-1: PHP vulnerabilities

Ubuntu • July 20, 2026

It was discovered that PHP incorrectly handled certain TLS setup failures, resulting in a NULL pointer dereference. An attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue only affected Ubuntu 26.04 LTS. ( CVE-2026-12184 ) It was discovered that PHP contained a buffer allocation flaw in the OpenSSL extension when using the AES-WRAP-PAD algorithm. An attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. ( CVE-2026-14355 )

In general, a standard system update will make all the necessary changes.

The problem can be corrected by updating your system to the following package versions:

Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
