Description

The _gnutls_x509_verify_certificate function in lib/x509/verify.c in libgnutls in GnuTLS before 2.6.1 trusts certificate chains in which the last certificate is an arbitrary trusted, self-signed certificate, which allows man-in-the-middle attackers to insert a spoofed certificate for any Distinguished Name (DN).

• gnu gnutls (< 2.6.1) • fedoraproject fedora 8 • fedoraproject fedora 9 • canonical ubuntu linux 6.06 • canonical ubuntu linux 7.10 • canonical ubuntu linux 8.04 • canonical ubuntu linux 8.10 • debian debian linux 4.0 • opensuse opensuse (>= 10.3 <= 11.1) • suse linux enterprise 10.0 • suse linux enterprise 11.0 • suse linux enterprise server 10 • suse linux enterprise server 11
