    Package        : gnutls13
    Vulnerability  : several
    Problem type   : remote
    Debian-specific: no
    CVE Id(s)      : CVE-2008-1948, CVE-2008-1949, CVE-2008-1950
    Several remote vulnerabilities have been discovered in GNUTLS, an
    implementation of the SSL/TLS protocol suite.
    NOTE: The libgnutls13 package, which provides the GNUTLS library, does
    not contain logic to automatically restart potentially affected
    services.  You must restart affected services manually (mainly Exim,
    using "/etc/init.d/exim4 restart") after applying the update, to make
    the changes fully effective.  Alternatively, you can reboot the system.
    The following vulnerabilities have been identified:
    A pre-authentication heap overflow involving oversized session
    resumption data may lead to arbitrary code execution (CVE-2008-1948).
    Repeated client hellos may result in a pre-authentication denial of
    service condition due to a null pointer dereference (CVE-2008-1949).
    Decoding cipher padding with an invalid record length may cause GNUTLS
    to read memory beyond the end of the received record, leading to a
    pre-authentication denial of service condition (CVE-2008-1950).
    For the stable distribution (etch), these problems have been fixed in
    version 1.4.4-3+etch1.  (Builds for the arm architecture are currently
    not available and will be released later.)
    For the unstable distribution (sid), these problems will be fixed soon. 
    We recommend that you upgrade your GNUTLS packages.
    Upgrade instructions
