Echo: nss: security update to 2:3.103-1

medium Tenable Cloud Security Plugin ID 458784

Description

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

 - Calling `PK11_Encrypt()` in NSS using CKM_CHACHA20 and the same buffer for input and output can result in
 plaintext on an Intel Sandy Bridge processor. In Firefox this only affects the QUIC header protection
 feature when the connection is using the ChaCha20-Poly1305 cipher suite. The most likely outcome is
 connection failure, but if the connection persists despite the high packet loss it could be possible for a
 network observer to identify packets as coming from the same source despite a network path change. This
 vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR < 128.1. (CVE-2024-7531)

Solution

Update the nss library and its related packages to version 2:3.103-1 or later.
