    Package : gnupg2
    Vulnerability : several
    Problem type : local (remote)
    Debian-specific: no
    CVE ID : CVE-2013-4351 CVE-2013-4402
    Debian Bug : 722724 725433

    Two vulnerabilities were discovered in GnuPG 2, the GNU privacy guard,
    a free PGP replacement. The Common Vulnerabilities and Exposures
    project identifies the following problems:

    CVE-2013-4351

    When a key or subkey had its "key flags" subpacket set to all bits
    off, GnuPG currently would treat the key as having all bits set.
    That is, where the owner wanted to indicate "no use permitted",
    GnuPG would interpret it as "all use permitted". Such "no use
    permitted" keys are rare and only used in very special circumstances.

    CVE-2013-4402

    Infinite recursion in the compressed packet parser was possible
    with crafted input data, which may be used to cause a denial of
    service.

    For the oldstable distribution (squeeze), these problems have been fixed in version 2.0.14-2+squeeze2.

    For the stable distribution (wheezy), these problems have been fixed in
    version 2.0.19-2+deb7u1.

    For the unstable distribution (sid), these problems have been fixed in
    version 2.0.22-1.

    We recommend that you upgrade your gnupg2 packages.
