Background ========== GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/gnutls < 3.5.13 >= 3.5.13 Description =========== A null pointer dereference while decoding a status response TLS extension with valid contents was discovered in GnuTLS. Impact ====== A remote attacker could possibly cause a Denial of Service condition. 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-3.5.13" Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.
