    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.
