openSUSE Leap 15.0: 2018:3012-1 Moderate: libX11 DoS Issues

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)
