        "Description": "This update upgrades libXfont2 to version 2.0.2-alt1. \nSecurity Fix(es):\n\n * CVE-2017-13720: 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.\n\n * CVE-2017-13722: In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server.",
