Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- PHP uses longjmp() for out-of-memory (OOM) errors to exit the current context and abort handling of the
request. Some contexts may not properly account for this scenario and leave request memory in an
uninitialized state before performing an allocation. The subsequent request cleanup procedure may read or
branch on this memory. Multiple OOM strategies can consistently trigger this condition and lead to remote
code execution (RCE). (CVE-2026-109618)

Solution

Update the php-8.2 library and its related packages to version 8.2.35+e1 or later.
