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.

 https://vulnerability.circl.lu/vuln/usn-2568-1 USN-2568-1 — libx11, libxrender vulnerability 2026-10-06T16:39:58.352078+00:00

Affected: Ubuntu:14.04:LTS: libxrender

Abhishek Arya discovered that libX11 incorrectly handled memory in the MakeBigReq macro. A remote attacker could use this issue to cause applications to crash, resulting in a denial of service, or possibly execute arbitrary code.

In addition, following the macro fix in libx11, a number of other packages have also been rebuilt as security updates including libxrender, libxext, libxi, libxfixes, libxrandr, libsdl1.2, libxv, libxp, and xserver-xorg-video-vmware.
