    Package        : exim-tls
    Vulnerability  : buffer overflow
    Problem-Type   : remote
    Debian-specific: no
    CVE ID         : CAN-2004-0399 CAN-2004-0400
    Georgi Guninski discovered two stack-based buffer overflows in exim
    and exim-tls.  They can not be exploited with the default
    configuration from the Debian system, though.  The Common
    Vulnerabilities and Exposures project identifies the following
    problems that are fixed with this update:
        When "sender_verify = true" is configured in exim.conf a buffer
        overflow can happen during verification of the sender.  This
        problem is fixed in exim 4.
        When headers_check_syntax is configured in exim.conf a buffer
        overflow can happen during the header check.  This problem does
        also exist in exim 4.
    For the stable distribution (woody) these problems have been fixed in
    version 3.35-3woody2.
    The unstable distribution (sid) does not contain exim-tls anymore.
    The functionality has been incorporated in the main exim versions
    which have these problems fixed in version 3.36-11 for exim 3 and in
    version 4.33-1 for exim 4.
    We recommend that you upgrade your exim-tls package.
