    Package        : libksba
    CVE ID         : CVE-2014-9087
    Debian Bug     : 770972
    
    An integer underflow flaw, leading to a heap-based buffer overflow, was
    found in the ksba_oid_to_str() function of libksba, an X.509 and CMS
    (PKCS#7) library. By using special crafted S/MIME messages or ECC based
    OpenPGP data, it is possible to create a buffer overflow, which could
    cause an application using libksba to crash (denial of service), or
    potentially, execute arbitrary code.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.2.0-2+deb7u1.
    
    For the upcoming stable distribution (jessie), this problem has been
    fixed in version 1.3.2-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.3.2-1.
    
    We recommend that you upgrade your libksba packages.
