Background
GnuTLS is an Open Source implementation of the TLS and SSL protocols.
Description
A flaw was reported in the TLS session ticket key construction in GnuTLS.
Impact
A remote attacker could recover previous conversations in TLS 1.2 and obtain sensitive information or conduct a man-in-the-middle attack to bypass authentication in TLS 1.3.
Workaround
There is no known workaround at this time.
Resolution
All GnuTLS user should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/gnutls-3.6.14"
| OS | Version | Architecture | Package | Version | Filename |
