GLSA-200505-04 : GnuTLS: Denial of Service vulnerability
Medium Nessus Plugin ID 18230
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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.
SolutionAll 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
