Description Prasad Pandit 2013-04-09 10:13:46 UTC

Linux kernel built with the Broadcom tg3 ethernet driver is vulnerable to a
buffer overflow. This could occur when the tg3 driver reads and copies firmware 
string from hardware's product data(VPD), if it exceeds 32 characters.

A user with physical access to a machine could use this flaw to crash the
system or, potentially, escalate their privileges on the system.

Comment 1 Prasad Pandit 2013-04-09 10:20:28 UTC

Statement:

This issue affects the versions of the Linux kernel as shipped with
Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2.

The Red Hat Security Response Team has rated this issue as having low security 
impact because physical access is needed to exploit this issue.  Future kernel 
updates for Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG 2 may 
address this issue. For additional information, refer to the Issue Severity 
Classification: https://access.redhat.com/security/updates/classification/.
