Descriptions
In libXfont before 1.5.4 and libXfont2 before 2.0.3, a local attacker can open (but not read) files on the system as root, triggering tape rewinds, watchdogs, or similar mechanisms that can be triggered by opening files.
En libXfont en versiones anteriores a la 1.5.4 y libXfont2 en versiones anteriores a la 2.0.3, un atacante local puede abrir (pero no leer) archivos en el sistema como root, desencadenando rebobinados de cinta, watchdogs o mecanismos similares que se pueden desencadenar abriendo archivos.
It was discovered that libXfont incorrectly followed symlinks when opening font files. A local unprivileged user could use this issue to cause the X server to access arbitrary files, including special device files.
