The vulnerability of the Unbound DNS server lies in its ability to generate a burst of requests to the server using responses from DNS resolvers. This allows a hacker to execute a DDoS attack by utilizing DNS traffic.

The vulnerability of the Unbound DNS server relates to the possibility of generating an impulsive flow of numerous requests to the server, using responses from DNS resolvers. Exploiting this vulnerability allows a malicious actor to carry out a DDoS attack by utilizing DNS traffic...

dnspython: denial of service in stub resolver

The dnspython stub resolver is vulnerable to a denial of service DoS risk if an attacker sends a malicious response forged with the correct address and port before a legitimate one arrives on the UDP port used by dnspython for the query. In such cases, dnspython could either switch to another...

Moderate: python-dns security update

The python-dns package contains the dnslib module that implements a DNS client and additional modules that define certain symbolic constants used by DNS, such as dnstype, dnsclass and dnsopcode. Security Fixes: dnspython: denial of service in stub resolver CVE-2023-29483 For more details about th...

CVE-2021-47360 binder: make sure fd closes complete

In the Linux kernel, the following vulnerability has been resolved: binder: make sure fd closes complete During BCFREEBUFFER processing, the BINDERTYPEFDA object cleanup may close 1 or more fds. The close operations are completed using the task work mechanism -- which means the thread needs to...

Important: unbound

Issue Overview: An issue was discovered in some DNS recursive resolvers that allows remote attackers to cause a denial of service using a maliciously designed authority and response amplification. CVE-2024-33655 Affected Packages: unbound Note: This advisory is applicable to Amazon Linux 2 -...

CVE-2023-52674

In the Linux kernel, the following vulnerability has been resolved: ALSA: scarlett2: Add clamp in scarlett2mixerctlput Ensure the value passed to scarlett2mixerctlput is between 0 and SCARLETT2MIXERMAXVALUE so we don't attempt to access outside scarlett2mixervalues...

bind9: KeyTrap - Extreme CPU consumption in DNSSEC validator

Processing specially crafted responses coming from DNSSEC-signed zones can lead to uncontrolled CPU usage, leading to a Denial of Service in the DNSSEC-validating resolver side. This vulnerability applies only for systems where DNSSEC validation is enabled...

c-ares: Out of bounds read in ares__read_line()

A vulnerability was found in c-ares where the aresreadline is used to parse local configuration files such as /etc/resolv.conf, /etc/nsswitch.conf, the HOSTALIASES file, and if using a c-ares version prior to 1.22.0, the /etc/hosts file. If the configuration files have an embedded NULL character ...

The default combination ...

unbound: unrestricted reconfiguration enabled to anyone that may lead to local privilege escalation

A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an...

bind9: Preparing an NSEC3 closest encloser proof can exhaust CPU resources

A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...
