More information:

Several security vulnerabilities have been discovered in smarty3, the compiling PHP template engine. Template authors are able to run restricted static php methods or even arbitrary PHP code by crafting a malicious math string or by choosing an invalid {block} or {include} file name. If a math string was passed through as user provided data to the math function, remote users were able to run arbitrary PHP code as well.

For the oldstable distribution (buster), these problems have been fixed in version 3.1.33+20180830.1.3a78a21f+selfpack1-1+deb10u1.

For the stable distribution (bullseye), these problems have been fixed in version 3.1.39-2+deb11u1.

We recommend that you upgrade your smarty3 packages.
