A null pointer dereference in GnuTLS might allow attackers to cause a Denial of Service condition.
|Package||net-libs/gnutls on all architectures|
|Affected versions||< 3.5.13|
|Unaffected versions||>= 3.5.13|
GnuTLS is a secure communications library implementing the SSL, TLS and DTLS protocols and technologies around them.
A null pointer dereference while decoding a status response TLS extension with valid contents was discovered in GnuTLS.
A remote attacker could possibly cause a Denial of Service condition.
There is no known workaround at this time.
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.
