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).
