6th percentile - higher than 6% of all known CVEs

Summary

Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it, or able to control the responses the application receives, may cause that application to stop running.

Risk Assessment

The risk is application denial of service (DoS) caused by an attacker who can deliberately trigger an error in decryption, potentially leading to service interruption.

Recommendation

It is recommended to update the encryption library to a patched version and to validate data size before decryption.
