Background
The Mozilla Network Security Service (NSS) is a library implementing security features like SSL v.2/v.3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME and X.509 certificates.
Description
NSS was found to not always perform constant-time operations when working with DSA key material.
Impact
An attacker may be able to obtain information about a DSA private key.
Workaround
There is no known workaround at this time.
Resolution
All NSS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/nss-3.52.1"
| OS | Version | Architecture | Package | Version | Filename |
|---|---|---|---|---|---|
| Gentoo | any | all | dev-libs/nss | < 3.52.1 | UNKNOWN |
