Amazon Linux 2023 Security Advisory: ALAS2023-2024-492
Advisory Released Date: 2024-01-22
Advisory Updated Date: 2024-01-22
Severity:
Medium
Issue Overview:
It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens before any padding operations, it affects all padding modes: PKCS#1 v1.5, OAEP, and RSASVP. Both API level calls and TLS server operation are affected. (CVE-2023-5388)
Affected Packages:
nss
Issue Correction:
Run dnf update nss --releasever 2023.3.20240122 or dnf update --advisory ALAS2023-2024-492 --releasever 2023.3.20240122 to update your system.
More information on how to update your system can be found on this page: Amazon Linux 2023 documentation
