Summary
[none]
Details

Integer underflow in grubnetrecvip4packets; A malicious crafted IP packet can lead to an integer underflow in grubnetrecvip4packets() function on rsm->totallen value. Under certain circumstances the totallen value may end up wrapping around to a small integer number which will be used in memory allocation. If the attack succeeds in such way, subsequent operations can write past the end of the buffer.
