Background ========== GnuTLS is a free TLS 1.0 and SSL 3.0 implementation for the GNU project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-libs/gnutls < 1.2.3 >= 1.2.3 *>= 1.0.25 Description =========== A vulnerability has been discovered in the record packet parsing in the GnuTLS library. Additionally, a flaw was also found in the RSA key export functionality. Impact ====== A remote attacker could exploit this vulnerability and cause a Denial of Service to any application that utilizes the GnuTLS library. Workaround ========== There is no known workaround at this time. Resolution ========== All GnuTLS users should remove the existing installation and upgrade to the latest version: # emerge --sync # emerge --unmerge gnutls # emerge --ask --oneshot --verbose net-libs/gnutls Due to small API changes with the previous version, please do the following to ensure your applications are using the latest GnuTLS that you just emerged. # revdep-rebuild --soname-regexp libgnutls.so.1[0-1] Previously exported RSA keys can be fixed by executing the following command on the key files: # certtool -k infile outfile References ========== [ 1 ] GnuTLS Announcement http://lists.gnupg.org/pipermail/gnutls-dev/2005-April/000858.html [ 2 ] CAN-2005-1431 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1431 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-04.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
