Alpine: bind: security update to 9.20.15-r0
high Tenable Cloud Security Plugin ID 435723
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Querying for records within a specially crafted zone containing certain malformed DNSKEY records can lead
to CPU exhaustion. This issue affects BIND 9 versions 9.18.0 through 9.18.39, 9.20.0 through 9.20.13,
9.21.0 through 9.21.12, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. (CVE-2025-8677)
- Under certain circumstances, BIND is too lenient when accepting records from answers, allowing an attacker
to inject forged data into the cache. This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0
through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1
through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1. (CVE-2025-40778)
- In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it
is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects
BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through
9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
