Buffer overflow

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...

CVE-2017-13722

CVE-2017-13722 affects libXfont (and libXfont2) prior to versions 2.0.2 and 1.5.3 respectively. The issue arises in the PCF font handling: in bitmap/pcfread.c within pcfGetProperties a missing boundary check on PCF files allows a local, authenticated attacker to induce a buffer over-read, leading...
