CVSS 3.0
7.1 highCVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:HCVE-2017-13720
High (7.1) in x.org libxfont. EPSS 0.4% chance of exploitation in the next 30 days.
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.
