8.5 HIGH — AV:N/AC:M/Au:S/C:C/I:C/A:C

Description

The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly handle character bitmaps it cannot read, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) and possibly execute arbitrary code via a crafted BDF font file.

Affected configurations

• canonical ubuntu linux 10.04 • canonical ubuntu linux 12.04 • canonical ubuntu linux 14.04 • canonical ubuntu linux 14.10 • debian debian linux 7.0 • x libxfont (<= 1.4.8) • x libxfont 1.5.0
