There is 1 open security issue in bullseye.
1 issue left for the package maintainer to handle:
Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP.
You can find information about how to handle this issue in the security team's documentation.
