CVE-2018-14598 [HIGH] CWE-20 CVE-2018-14598: An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server 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-2016-7943 [CRITICAL] CWE-787 CVE-2016-7943: The XListFonts function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges The XListFonts function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges via vectors involving length fields, which trigger out-of-bounds write operations.

CVE-2016-7942 [CRITICAL] CWE-264 CVE-2016-7942: The XGetImage function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges The XGetImage function in X.org libX11 before 1.6.4 might allow remote X servers to gain privileges via vectors involving image type and geometry, which triggers out-of-bounds read operations.

CVE-2013-7439 [HIGH] CWE-189 CVE-2013-7439: Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h i Multiple off-by-one errors in the (1) MakeBigReq and (2) SetReqLen macros in include/X11/Xlibint.h in X11R6.x and libX11 before 1.6.0 allow remote attackers to have unspecified impact via a crafted request, which triggers a buffer overflow.
