In Modem, there is a possible system crash due to a logic error. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01412526; Issue ID: MSV-2018.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Potential Mitigations
- Make fields transient to protect them from deserialization.
- An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
