CVE-2014-5409

CVE-2014-5409 affects GE Digital Energy Hydran M2 devices with the 17046 Ethernet option. The 17046 Ethernet card before 94450214LFMT100SEM-L.R3-CL does not generate proper random TCP Initial Sequence Numbers, enabling an attacker to predict sequence values and spoof packets. Exploitation could b...

CVE-2014-5409 GE Hydran M2 Predictable Value Range from Previous Values

The 17046 Ethernet card before 94450214LFMT100SEM-L.R3-CL for the GE Digital Energy Hydran M2 does not properly generate random values for TCP Initial Sequence Numbers ISNs, which makes it easier for remote attackers to spoof packets by predicting these values...

Design/Logic Flaw

The netgetrandomonce implementation in net/core/utils.c in the Linux kernel 3.13.x and 3.14.x before 3.14.5 on certain Intel processors does not perform the intended slow-path operation to initialize random seeds, which makes it easier for remote attackers to spoof or disrupt IP communication by...

CVE-2014-7284

CVE-2014-7284 affects the Linux kernel’s net_get_random_once in net/core/utils.c for 3.13.x and 3.14.x before 3.14.5 on certain Intel CPUs. The issue is that the slow-path to seed randomness is not executed, increasing predictability of TCP sequence numbers, TCP/UDP port numbers, and IP ID values...
