Out-of-bounds Write
Detailed paths
NVD Description
Note: Versions mentioned in the description apply only to the upstream zlib package and not the zlib package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
zlib versions 1.3.1.2 through 1.3.2 contain a heap buffer overflow vulnerability in the gz_vacate() function when processing non-blocking gzwrite() operations with stale external buffer pointers. Attackers can trigger the overflow by calling gzprintf() or gzvprintf() after a write stall, causing an unchecked memmove() to write beyond the internal input buffer boundary.
Remediation
Upgrade Alpine:3.24 zlib to version 1.3.2-r1 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
A BIND resolver encountering an SVCB/HTTPS AliasMode record referencing 14 or more SVCB/HTTPS ServiceMode records may fail to properly deallocate internal resources. If this happens repeatedly, resource exhaustion will eventually prevent the resolver from performing new recursive lookups. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
Remediation
Upgrade Alpine:3.24 bind to version 9.20.29-r0 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
If a BIND resolver has cached a tree of SVCB/HTTPS AliasMode records, and is then queried for the root of that tree, the resolver will spend disproportionate CPU time constructing the response. This issue affects BIND 9 versions 9.18.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.18.11-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
Remediation
Upgrade Alpine:3.24 bind to version 9.20.29-r0 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
If an attacker-controlled authoritative server can produce a negative answer that is exactly 65536 bytes, then a flaw in named results in a negative cache entry of 0 bytes. When this entry is subsequently read, named aborts.
This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
Remediation
Upgrade Alpine:3.24 bind to version 9.20.29-r0 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream bind package and not the bind package as distributed by Alpine.
See How to fix? for Alpine:3.24 relevant fixed versions and status.
If a BIND resolver sends a query for a DNSSEC-signed authoritative zone, and the authoritative server replies with a valid wildcard answer and signed NSEC3 proof, followed by an unsigned NSEC at the same owner name, it will trigger an unexpected program exit. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.
Remediation
Upgrade Alpine:3.24 bind to version 9.20.29-r0 or higher.

NVD Description

See How to fix? for Alpine:3.24 relevant fixed versions and status.
If BIND is loaded with a "named.conf" file that contains no global "options" block, an attacker can send a query of QTYPE TKEY which may cause an assertion failure and subsequent unexpected program exit.
This issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, and 9.20.9-S1 through 9.20.27-S1.
Remediation
Upgrade Alpine:3.24 bind to version 9.20.29-r0 or higher.
