Synopsis ========
Multiple vulnerabilities have been discovered in GnuTLS, the worst of which could lead to Denial of Service.
Background ==========
GnuTLS is an Open Source implementation of the TLS 1.2 and SSL 3.0 protocols.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/gnutls < 2.12.23-r1 >= 2.12.23-r1
Description ===========
Multiple vulnerabilities have been discovered in GnuTLS. Please review the CVE identifiers and Lucky Thirteen research paper referenced below for details.
Impact ======
A remote attacker could sent a specially crafted packet to cause a Denial of Service condition. Additionally, a remote attacker could perform man-in-the-middle attacks to recover plaintext data.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All GnuTLS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-libs/gnutls-2.12.23-r1"
