Description

Affected products do not properly sanitize user-controllable input when parsing files. This could allow an attacker to cause a type confusion and execute arbitrary code within the affected application. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends countermeasures for products where fixes are not, or not yet available.
