Jon Larimer from IBM X-Force Advanced Research discovered multiple vulnerabilities in the DVI backend of the Evince document viewer:
Insufficient array bounds checks in the PK fonts parser could lead to function pointer overwrite, causing arbitrary code execution.
Insufficient array bounds checks in the VF fonts parser could lead to function pointer overwrite, causing arbitrary code execution.
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.
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.
