    Package        : nbd
    CVE ID         : CVE-2013-7441 CVE-2015-0847
    Debian Bug     : 781547 784657
    
    Tuomas Räsänen discovered that unsafe signal handling in nbd-server, the
    server for the Network Block Device protocol, could allow remote
    attackers to cause a deadlock in the server process and thus a denial of
    service.
    
    Tuomas Räsänen also discovered that the modern-style negotiation was
    carried out in the main server process before forking the actual client
    handler. This could allow a remote attacker to cause a denial of service
    (crash) by querying a non-existent export. This issue only affected the
    oldstable distribution (wheezy).
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 1:3.2-4~deb7u5.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1:3.8-4+deb8u1.
    
    For the testing distribution (stretch), these problems have been fixed
    in version 1:3.10-1.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1:3.10-1.
    
    We recommend that you upgrade your nbd packages.
