Discussion
X.Org libX11 'MakeBigReq()' Macro Buffer Overflow Vulnerability
The 'libX11' library is prone to a buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it into an insufficiently sized buffer.
Attackers can exploit this issue to execute arbitrary code within the context of the application. Failed attacks may cause a denial-of-service condition.
