Running "# glsa-check -t all" on a machine with xfree-4.3.0-r5 installed, I was told that my machine was affected by GLSA 200402-02 (XFree86 Font Information File Buffer Overflow). However, the documentation provided at http://www.gentoo.org/security/en/glsa/glsa-200402-02.xml states that "Vulnerable versions are no longer available in Portage", and that 4.3.0-r4 was bug free. Don't know whether it is relevant, but I'm running gentoo-sources 2.4.25 on a pentium4.
