Persistent client crash loop via undersized FLE2 insert-update ciphertext in decryption path
Fix: upgrade to 1.20.4 or later
Impact
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.
Patches
Fixed in 1.20.4
Workarounds
None.
