Red Hat Product Errata RHSA-2014:1436 normal SHIPPED_LIVE Moderate: X11 client libraries security, bug fix, and enhancement update 2014-10-14 01:06:02 UTC

Description Huzaifa S. Sidhpurwala 2013-05-07 06:23:55 UTC
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.
