CVE-2013-2064 libxcb: Integer overflow leading to heap-based buffer overflow
Last modified: 2014-10-17 03:47:46 EDT
An integer overflow leading to a heap-based buffer overflow was found in the read_packet() function of the libxcb library, the X protocol C-language Binding (XCB) library. When a X client is connected to a malicious X server, (modified to return invalid values), it can cause arbirary code execution with the privileges of the user running the X client.
