Description

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.

Solution(s)

  • gentoo-linux-upgrade-x11-libs-libxfont
  • gentoo-linux-upgrade-x11-libs-libxfont2
