CVE-2010-3298: Infoleak
First published: Mon Sep 13 2010(Updated: )
Description of problem: <a href="http://lkml.org/lkml/2010/9/11/167">http://lkml.org/lkml/2010/9/11/167</a> The TIOCGICOUNT device ioctl allows unprivileged users to read 9 bytes of uninitialized stack memory, because the "reserved" member of the serial_icounter_struct struct declared on the stack in hso_get_count() is not altered or zeroed before being copied back to the user. This patch takes care of it. Acknowledgements: Red Hat would like to thank Dan Rosenberg for reporting this issue.
