649717: CVE-2010-3877 kernel: net/tipc/socket.c: reading uninitialized stack memory

The MITRE CVE dictionary describes this issue as:

The get_name function in net/tipc/socket.c in the Linux kernel before 2.6.37-rc2 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure.

Find out more about CVE-2010-3877 from the MITRE CVE dictionary dictionary and NIST NVD.


This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for Transparent Inter-Process Communication Protocol (TIPC). A future
kernel update in Red Hat Enterprise Linux 5 may address this flaw.
