SCA: security update for github.com/cloudflare/circl (GHSA-2q89-485c-9j2x)

high Tenable Self-Hosted Container Security Plugin ID 409036

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)
