Name of the Vulnerable Software and Affected Versions
libXfont versions prior to 1.5.2 and 2.x before 2.0.2
Description
A missing boundary check in the
pcfGetProperties function in bitmap/pcfread.c could allow local attackers authenticated to an X server to perform a buffer over-read. This could lead to information disclosure or cause the X server to crash.Recommendations
For libXfont versions prior to 1.5.2, update to version 1.5.2 or later.
For libXfont 2.x versions before 2.0.2, update to version 2.0.2 or later.
As a temporary workaround, consider restricting access to the
pcfGetProperties function in bitmap/pcfread.c until a patch is available.Correção
