commit: https://git.buildroot.net/buildroot/commit/?id=e2d8ee3bec618cc043ba5a720763de4dda38017f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

Fixes the following security issues (1.1.1e):

CVE-2019-1551 [Low severity]: There is an overflow bug in the x64_64
Montgomery squaring procedure used in exponentiation with 512-bit moduli.
No EC algorithms are affected.  Analysis suggests that attacks against
2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect
would be very difficult to perform and are not believed likely.  Attacks
against DH512 are considered just feasible.  However, for an attack the
target would have to re-use the DH512 private key, which is not recommended
anyway.  Also applications directly using the low level API BN_mod_exp may
be affected if they use BN_FLG_CONSTTIME.  Reported by OSS-Fuzz and Guido
Vranken.

CVE-2019-1563 [Low severity]: In situations where an attacker receives
automated notification of the success or failure of a decryption attempt an
attacker, after sending a very large number of messages to be decrypted, can
recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted
message that was encrypted with the public RSA key, using a Bleichenbacher
padding oracle attack.  Applications are not affected if they use a
certificate together with the private RSA key to the CMS_decrypt or
PKCS7_decrypt functions to select the correct recipient info to decrypt.
Reported by Bernd Edlinger.
