(CVE-2007-2754)\n\nA flaw was discovered in the FreeType TTF font-file format parser when the\nTrueType virtual machine Byte Code Interpreter (BCI) is enabled. If a user\nloaded a carefully-crafted font file with an application linked against\nFreeType, it could cause the application to crash or, possibly, execute\narbitrary code with the privileges of the user running the application.\n(CVE-2008-1808)\n\nThe CVE-2008-1808 flaw did not affect the freetype packages as distributed\nin Red Hat Enterprise Linux 3 and 4, as they are not compiled with TrueType\nBCI support. A fix for this flaw has been included in this update as users\nmay choose to recompile the freetype packages in order to enable TrueType\nBCI support. Red Hat does not, however, provide support for modified and\nrecompiled packages.\n\nNote: For the FreeType 2 font engine, the CVE-2006-1861, CVE-2007-2754,\nand CVE-2008-1808 flaws were addressed via RHSA-2006:0500, RHSA-2007:0403,\nand RHSA-2008:0556 respectively. This update provides corresponding\nupdates for the FreeType 1 font engine, included in the freetype packages\ndistributed in Red Hat Enterprise Linux 3 and 4.\n\nUsers are advised to upgrade to these updated packages, which contain\nbackported patches to correct these issues.
