NSS has an information disclosure vulnerability when handling DSA keys.
|Package||dev-libs/nss on all architectures|
|Affected versions||< 3.52.1|
|Unaffected versions||>= 3.52.1|
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.
NSS was found to not always perform constant-time operations when working with DSA key material.
An attacker may be able to obtain information about a DSA private key.
There is no known workaround at this time.
All NSS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/nss-3.52.1"
