The vulnerability of the srxpfe process in the JunOS operating system allows a hacker to cause failures in the service switches.

The vulnerability of the srxpfe process in the JunOS operating system is related to an uncontrolled consumption of resources. Exploiting this vulnerability can allow a malicious actor, operating remotely, to cause failures in the service switches by using a specially crafted fragmented HTTP packe...

CVE-2019-0052

The srxpfe process may crash on SRX Series services gateways when the UTM module processes a specific fragmented HTTP packet. The packet is misinterpreted as a regular TCP packet which causes the processor to crash. This issue affects all SRX Series platforms that support URL-Filtering and have...

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-2019-11478 SACK can cause extensive memory use via fragmented resend queue

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...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of serviceDoS attacks. This is because of the way Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted...

Arbitrary Code Execution

Linux kernel is vulnerable to buffer overflow vulnerability. This is due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. Remote attackers could execute arbitrary code via crafted...

kernel: Buffer overflow in firewire driver via crafted incoming packets

A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 year 2009 till...

The vulnerability of the TCP/IP protocol implementation in the Windows operating system allows a perpetrator to compromise the confidentiality of the protected information.

The vulnerability of the TCP/IP protocol implementation in the Windows operating system is related to the lack of protection for service data. Exploiting this vulnerability allows a malicious actor to compromise the confidentiality of protected information by using specially crafted fragmented IP...

CVE-2019-0688

An information disclosure vulnerability exists when the Windows TCP/IP stack improperly handles fragmented IP packets, aka 'Windows TCP/IP Information Disclosure Vulnerability'...

Windows TCP/IP Information Disclosure Vulnerability

An information disclosure vulnerability exists when the Windows TCP/IP stack improperly handles fragmented IP packets. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system. To exploit this vulnerability, an attacker would have ...

CVE-2018-15840

CVE-2018-15840 affects TP-Link TL-WR840N devices: a vulnerability in processing fragmented packets can be exploited remotely to cause a denial of service (network outage). Demonstrated by sending fragmented packets (e.g., with nmap -f). The provided connected documents corroborate a DoS impact vi...
