Dear all,

Network Security Services (NSS) 3.90.2 was tagged and released
on 15th February 2024.

The HG tag is NSS_3_90_2_RTM. This version of NSS requires NSPR
4.35 or newer.

NSS 3.90.2 source distributions are available on ftp.mozilla.org
for secure HTTPS download:


- Bug 1780432 - (CVE-2023-5388) Timing attack against RSA
decryption in TLS.
- Bug 1867408 - add a defensive check for large ssl_DefSend
return values.

NSS 3.90.2 shared libraries are backwards-compatible with all
older NSS 3.x shared libraries. A program linked with older NSS
3.x shared libraries will work with this new version of the
shared libraries without recompiling or relinking. Furthermore,
applications that restrict their use of NSS APIs to the
functions listed in NSS Public Functions will remain compatible
with future versions of the NSS shared libraries.

Bugs discovered should be reported by filing a bug report at
