    Package        : squirrelmail
    Vulnerability  : No user-specific token implemented
    Problem type   : remote
    Debian-specific: no
    Debian bug     : 543818
    CVE ID         : CVE-2009-2964 CVE-2010-2813
    
    SquirrelMail, a webmail application, does not employ a user-specific token 
    for webforms. This allows a remote attacker to perform a Cross Site Request 
    Forgery (CSRF) attack. The attacker may hijack the authentication of 
    unspecified victims and send messages or change user preferences among other 
    actions, by tricking the victim into following a link controled by the 
    offender.
    
    In addition, a denial-of-service was fixed, which could be triggered when a 
    passwords containing 8-bit characters was used to log in (CVE-2010-2813).
    
    For the stable distribution (lenny), these problems have been fixed in
    version 1.4.15-4+lenny3.1.
    
    For the testing distribution (squeeze) and the unstable distribution (sid),
    these problems have been fixed in version 1.4.21-1.
    
    We recommend that you upgrade your squirrelmail packages.
