    It has been discovered that in barnowl, a curses-based instant-messaging
    client, the return codes of calls to the ZPending and ZReceiveNotice
    functions in libzephyr were not checked, allowing attackers to cause a
    denial of service (crash of the application), and possibly execute
    arbitrary code.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.0.1-4+lenny2.
    
    For the testing distribution (squeeze), this problem has been fixed in
    version 1.6.2-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.6.2-1.
    
    We recommend that you upgrade your barnowl packages.
