Ubuntu 9.04 : smarty vulnerability (USN-791-3)

Critical Nessus Plugin ID 39518


The remote Ubuntu host is missing a security-related patch.


It was discovered that Smarty did not correctly filter certain math inputs. A remote attacker using Smarty via a web service could exploit this to execute subsets of shell commands as the web server user.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected smarty package.
