    Debian Bug     : 609534
    
    Jon Larimer from IBM X-Force Advanced Research discovered multiple
    vulnerabilities in the DVI backend of the evince document viewer:
    
    CVE-2010-2640
    
        Insuficient array bounds checks in the PK fonts parser could lead
        to function pointer overwrite, causing arbitrary code execution.
    
    CVE-2010-2641
    
        Insuficient array bounds checks in the PK fonts parser could lead
        to function pointer overwrite, causing arbitrary code execution.
    
    CVE-2010-2642
    
        Insuficient bounds checks in the AFM fonts parser when writing
        data to a memory buffer allocated on heap could lead to arbitrary
        memory overwrite and arbitrary code execution.
    
    CVE-2010-2643
    
        Insuficient check on an integer used as a size for memory
        allocation can lead to arbitrary write outside the allocated range
        and cause arbitrary code execution.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 2.22.2-4~lenny2.
    
    For the stable distribution (squeeze), CVE-2010-2640, CVE-2010-2641
    and CVE-2010-2643 have been fixed in version 2.30.3-2 but the fix for
    CVE-2010-2642 was incomplete. The final fix is present in version
    2.30.3-2+squeeze1.
    
    For the testing distribution (wheezy), this problem has been fixed in
    version 3.0.2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 3.0.2.
    
    We recommend that you upgrade your evince packages.
