    Package        : gnupg
    Vulnerability  : several
    Problem-Type   : local(remote)
    Debian-specific: no
    CVE ID         : CVE-2007-1263
    Debian Bug     : 413922 414170
    Gerardo Richarte discovered that GnuPG, a free PGP replacement, provides
    insufficient user feedback if an OpenPGP message contains both unsigned
    and signed portions. Inserting text segments into an otherwise signed
    message could be exploited to forge the content of signed messages.
    This update prevents such attacks; the old behaviour can still be
    activated by passing the --allow-multiple-messages option.
    For the stable distribution (sarge) these problems have been fixed in
    version 1.4.1-1.sarge7.
    For the upcoming stable distribution (etch) these problems have been
    fixed in version 1.4.6-2.
    For the unstable distribution (sid) these problems have been fixed in
    version 1.4.6-2.
    We recommend that you upgrade your gnupg packages.
