Description Huzaifa S. Sidhpurwala 2013-05-03 06:17:12 UTC

An integer overflow leading to heap-based buffer overflow was found in the _XcursorFileHeaderCreate() function of libXcursor a simple library designed to help locate and load cursors. If an X client read a malicious user-specified config file, when connecting to an X server, it could result in arbitrary code execution with the privileges of the user running the X client process.
