There is no fixed version for Debian:9 libxfont1.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxfont1 package and not the libxfont1 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server.
