CVE-2019-11477

Jonathan Looney discovered that the TCPSKBCBskb-tcpgsosegs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments SACKs. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182,...

DEBIAN-CVE-2019-11478

Jonathan Looney discovered that the TCP retransmission queue implementation in tcpfragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment SACK sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel...

CVE-2019-11479

Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kerne...
