Added CVE as per http://www.openwall.com/lists/oss-security/2012/03/06/16 This flaw is in the TrueType bytecode interpreter (BCI) implementation. BCI is not enabled in Red Hat Enterprise Linux 4, 5, and 6 freetype packages (it was disabled by default upstream because of the patent concerns). BCI support is now enabled by default in upstream versions 2.4 and later, as relevant patents expired: http://www.freetype.org/patents.html Statement: Not vulnerable. This issue did not affect freetype packages as shipped with Red Hat Enterprise Linux 5 and 6, as they do not enable TrueType bytecode interpreter. |
