libgcrypt: Remediation for side-channel attack on Elgamal encryption subkeys
libgcrypt was updated to 1.5.4 to prevent a side-channel attack on Elgamal encryption subkeys.
Besides that the following issues were resolved:
- Improved performance of RSA, DSA, and Elgamal by using a new exponentiation algorithm.
- Fixed a subtle bug in mpi_set_bit which could set spurious bits.
- Fixed a bug in an internal division function.
- Submitted by Andreas Stieger (AndreasStieger)
