Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:
- When sampling randomness for a shared secret, the implementation of Kyber and FrodoKEM, did not check
whether crypto/rand.Read() returns an error. In rare deployment cases (error thrown by the Read()
function), this could lead to a predictable shared secret. The tkn20 and blindrsa components did not check
whether enough randomness was returned from the user provided randomness source. Typically the user
provides crypto/rand.Reader, which in the vast majority of cases will always return the right number
random bytes. In the cases where it does not, or the user provides a source that does not, the blinding
for blindrsa is weak and integrity of the plaintext is not ensured in tkn20. (CVE-2023-1732)
Solution
Update the amazon-ssm-agent library and its related packages to version 2.3.6 or later.
