  "details": "In the PatternMatch function in fontfile/fontdir.c in libXfont through\n1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection\ncan cause a buffer over-read during pattern matching of fonts, leading\nto information disclosure or a crash (denial of service). This occurs\nbecause '\\0' characters are incorrectly skipped in situations involving\n? characters. (CVE-2017-13720)\n\nIn the pcfGetProperties function in bitmap/pcfread.c in libXfont through\n1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files)\ncould be used by local attackers authenticated to an Xserver for a\nbuffer over-read, for information disclosure or a crash of the X server.\n(CVE-2017-13722)\n",
