   An update that fixes three vulnerabilities is now available.

Description:

   This update for xorg-x11-libX11 fixes the following issues:

   - CVE-2018-14599: The function XListExtensions was vulnerable to an
     off-by-one error caused by malicious server responses, leading to DoS or
     possibly unspecified other impact (bsc#1102062)
   - CVE-2018-14600: The function XListExtensions interpreted a variable as
     signed instead of unsigned, resulting in an out-of-bounds write (of up
     to 128 bytes), leading to DoS or remote code execution (bsc#1102068)
   - CVE-2018-14598: A malicious server could have sent a reply in which the
     first string overflows, causing a variable to be set to NULL that will
     be freed later
     on, leading to DoS (segmentation fault) (bsc#1102073)
