Description

Jon Larimer from IBM X-Force Advanced Research discovered multiple vulnerabilities in the DVI backend of the Evince document viewer :

  • CVE-2010-2640 Insufficient array bounds checks in the PK fonts parser could lead to function pointer overwrite, causing arbitrary code execution.

  • CVE-2010-2641 Insufficient array bounds checks in the VF fonts parser could lead to function pointer overwrite, causing arbitrary code execution.

  • CVE-2010-2642 Insufficient 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 Insufficient 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.

CVE-2010-2642 was incomplete. The final fix is present in version
