Vulnerability Assessment Details
GnuTLS: Denial of Service vulnerability
Detailed Explanation for this Vulnerability Assessment
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.
A remote attacker could exploit this vulnerability and cause a
Denial of Service to any application that utilizes the GnuTLS library.
There is no known workaround at this time.
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
Network Security Threat Level: Medium
