Description

Several local vulnerabilities have been discovered in freetype, a FreeType 2 font engine, which could allow the execution of arbitrary code.

The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2008-1806 An integer overflow allows context-dependent attackers to execute arbitrary code via a crafted set of values within the Private dictionary table in a Printer Font Binary (PFB) file.

  • CVE-2008-1807 The handling of an invalid

    An integer overflow allows context-dependent attackers

  - CVE-2008-1807

    locations, leading to memory corruption.

  - CVE-2008-1808
