UBUNTU-CVE-2022-32296

The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used. This occurs because of use of Algorithm 4 "Double-Hash Port Selection Algorithm" of RFC 6056...

CVE-2022-32296

CVE-2022-32296 affects the Linux kernel where, prior to 5.17.9, the TCP source port selection (Algorithm 4, Double-Hash Port Selection from RFC 6056) can allow a remote or local observer to identify clients by observed source ports. Connected advisories confirm the issue in kernel ments and note ...

USN-4976-1 dnsmasq vulnerability

Petr Mensik discovered that Dnsmasq incorrectly randomized source ports in certain configurations. A remote attacker could possibly use this issue to facilitate DNS cache poisoning attacks...

CVE-2018-2599

It was discovered that the DNS client implementation in the JNDI component of OpenJDK did not use random source ports when sending out DNS queries. This could make it easier for a remote attacker to spoof responses to those queries...

Huawei E5186 4G LTE Router Security Bypass Vulnerability

Huawei E5186 4G LTE Router is a 4G wireless router product from Huawei, China. The Huawei E5186 4G LTE Router allows DNS query packets to use static source ports, allowing remote attackers to exploit this vulnerability to forge responses...

Mozilla Firefox for Android DNS Spoofing Vulnerability

Mozilla Firefox is a popular web browser, and Google Android is a Linux-based open source operating system used mainly in portable devices. A security vulnerability exists in Mozilla Firefox for Android DNS resolution, as the PRNG implementation in DNS resolver fails to correctly use time and PID...

CVE-2014-4883

resolv.c in the DNS resolver in uIP, and dns.c in the DNS resolver in lwIP 1.4.1 and earlier, does not use random values for ID fields and source ports of DNS query packets, which makes it easier for man-in-the-middle attackers to conduct cache-poisoning attacks via spoofed reply packets...

Nmap NSE 6.01: dns-random-srcport

Checks a DNS server for the predictable-port recursion vulnerability. Predictable source ports can make a DNS server vulnerable to cache poisoning attacks see CVE-2008-1447. The script works by querying porttest.dns-oarc.net see https://www.dns- oarc.net/oarc/services/porttest. Be aware that any...

Scientific Linux Security Update : bind on SL 3.0.x , SL 4.x, SL 5.x

The DNS protocol protects against spoofing attacks by requiring an attacker to predict both the DNS transaction ID and UDP source port of a request. In recent years, a number of papers have found problems with DNS implementations which make it easier for an attacker to perform DNS cache-poisoning...

Nmap NSE net: dns-random-srcport

Checks a DNS server for the predictable-port recursion vulnerability. Predictable source ports can make a DNS server vulnerable to cache poisoning attacks see CVE-2008-1447. The script works by querying porttest.dns-oarc.net see https://www.dns- oarc.net/oarc/services/porttest. Be aware that any...

USN-1008-1: libvirt vulnerabilities

It was discovered that libvirt would probe disk backing stores without consulting the defined format for the disk. A privileged attacker in the guest could exploit this to read arbitrary files on the host. This issue only affected Ubuntu 10.04 LTS. By default, guests are confined by an AppArmor...

Multiple Cisco Products Vulnerable to DNS Cache Poisoning Attacks

Multiple Cisco products are vulnerable to DNS cache poisoning attacks due to their use of insufficiently randomized DNS transaction IDs and UDP source ports in the DNS queries that they produce, which may allow an attacker to more easily forge DNS answers that can poison DNS caches. To exploit th...
