Description

This security bulletin contains information about 3 vulnerabilities.


1) Insufficient verification of data authenticity (CVE-ID: CVE-2025-40778)

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to poison DNS cache.

The vulnerability exists due to insufficient verification of data authenticity when accepting records from answers. A remote attacker can inject forged data into the cache leading to DNS cache poisoning. 


2) Predictable Seed in Pseudo-Random Number Generator (PRNG) (CVE-ID: CVE-2025-40780)

CWE-ID: CWE-337 - Predictable Seed in Pseudo-Random Number Generator (PRNG)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to poison DNS cache.

The vulnerability exists due to weakness in the Pseudo Random Number Generator (PRNG). A remote attacker can predict the source port and query ID that BIND will use and perform DNS cache poisoning attacks.


3) Resource exhaustion (CVE-ID: CVE-2025-8677)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when querying for data within a specially crafted zone containing certain malformed DNSKEY records. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
