Amazon Linux 2023 Security Advisory: ALAS2023-2024-727
Advisory Released Date: 2024-10-14
Advisory Updated Date: 2024-10-14
Severity:
Medium
Issue Overview:
Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key. (CVE-2024-41996)
Affected Packages:
openssl
Issue Correction:
Run dnf update openssl --releasever 2023.6.20241010 or dnf update --advisory ALAS2023-2024-727 --releasever 2023.6.20241010 to update your system.
