This update for libX11 fixes the following security 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)
