Descriptions
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Unprivileged users may be able to access privileged kernel data.
En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, la validación insuficiente de parámetros de fuente proporcionados por el usuario pueden resultar en un desbordamiento de enteros que conduce al uso de memoria arbitraria del kernel como datos glyph. Los usuarios sin privilegios podrían ser capaces de acceder a datos privilegiados del kernel.
