-
CVE-2024-7531: 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.
