In the PatternMatch function in fontfile/fontdir.c in libXfont through
1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can
cause a buffer over-read during pattern matching of fonts, leading to
information disclosure or a crash (denial of service). This occurs because
‘\0’ characters are incorrectly skipped in situations involving ?
characters.
