CVE-2010-3874

[Andy Whitcroft]

Heap-based buffer overflow in the bcm_connect function in net/can/bcm.c
(aka the Broadcast Manager) in the Controller Area Network (CAN)
implementation in the Linux kernel before 2.6.36.2 on 64-bit platforms
might allow local users to cause a denial of service (memory corruption)
via a connect operation.

The commit below is the upstream fix for this:

    can-bcm: fix minor heap overflow

    On 64-bit platforms the ASCII representation of a pointer may be up to 17
    bytes long. This patch increases the length of the buffer accordingly.

This patch has hit Maverick via the upstream stable process and was released in Ubuntu-2.6.35-25.43, as that is already in updates.

[Andy Whitcroft (apw)]

This patch has hit Lucid via the upstream stable process and was released in 2.6.32-28.55, as that is already in updates closing Fix Released.

[Andy Whitcroft (apw)]

This network protocol was not added to the kernel until v2.6.25 and therefore does not affect Dapper or Hardy.
