Description
An out of bounds write, limited to NULL bytes, was discovered in libX11 in functions XListExtensions() and XGetFontPath(). The length field is considered as a signed value, which makes the library access memory before the intended buffer. An attacker who can either configure a malicious X server or modify the data coming from one could use this flaw to make the program crash or have other unspecified effects, caused by the memory corruption.
