   An update that solves three vulnerabilities and has one
   errata is now available.

Description:

   This update for libX11 and libxcb fixes the following issue:

   libX11:

   These security issues were fixed:

   - 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).

   This non-security issue was fixed:

   - Make use of the new 64-bit sequence number API in XCB 1.11.1 to avoid
     the 32-bit sequence number wrap in libX11 (bsc#1094327).

   libxcb:

   - Expose 64-bit sequence number from XCB API so that Xlib and others can
     use it even
     on 32-bit environment. (bsc#1094327)
