Echo: libgcrypt20: security update to 1.10.1-3

high Tenable Self-Hosted Container Security Plugin ID 458003

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes
plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it
does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH)
assumption does not hold for Libgcrypt's ElGamal implementation. (CVE-2018-6829)

Solution

Update the libgcrypt20 library and its related packages to version 1.10.1-3 or later.
