smarty3 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.10
- Ubuntu 22.04 LTS

Summary:

Smarty could be made to crash or run programs if it received a specially
crafted template.

Software Description:
- smarty3: The compiling PHP template engine

Details:

It was discovered that Smarty incorrectly parsed blocks` names and
included files` names. A remote attacker with template writing permissions
could use this issue to execute arbitrary PHP code. (CVE-2022-29221)

Update instructions:

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

Ubuntu 22.10:
   smarty3                         3.1.39-2ubuntu1.22.10.1

Ubuntu 22.04 LTS:
   smarty3                         3.1.39-2ubuntu1.22.04.1

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