Linux Kernel Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA19330

VERIFY ADVISORY:
http://secunia.com/advisories/19330/

CRITICAL:
Moderately critical

IMPACT:
Unknown

WHERE:
>From remote

OPERATING SYSTEM:
Linux Kernel 2.6.x
http://secunia.com/product/2719/

DESCRIPTION:
Two vulnerabilities have been reported in the Linux Kernel, which has
an unknown impact.

1) An integer overflow error exists within the "do_replace()"
function in Netfilter. This can be exploited to cause a buffer
overflow and allows the overwrite of arbitrary amounts of kernel
memory when data is copied from user space.

2) Insufficient memory allocation in "drivers/usb/gadget/rndis.c"
when handling NDIS response to OID_GEN_SUPPORTED_LIST may cause
kernel memory corruption.

SOLUTION:
Update to version 2.6.16.

2) Shaun Tancheff
