Synopsis

Description

The remote host is affected by the vulnerability described in GLSA-200505-04 (GnuTLS: Denial of Service vulnerability)

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.

Solution

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
