An issue was discovered in XListExtensions in ListExt.c in libX11 through
1.6.5. A malicious server can send 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) (CVE-2018-14598).

An issue was discovered in libX11 through 1.6.5. The function
XListExtensions in ListExt.c is vulnerable to an off-by-one error caused
by malicious server responses, leading to DoS or possibly unspecified
other impact (CVE-2018-14599).

An issue was discovered in libX11 through 1.6.5. The function
XListExtensions in ListExt.c interprets 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 (CVE-2018-14600).");
