Title
Aardvark-dns has incorrect error handling for malformed tcp packets
Summary
Aardvark-dns is an authoritative dns server for A/AAAA container records. From 1.16.0 to 1.17.0, a truncated TCP DNS query followed by a connection reset causes aardvark-dns to enter an unrecoverable infinite error loop at 100% CPU. This vulnerability is fixed in 1.17.1.

Title
Containers/aardvark-dns: tcp query handling flaw in aardvark-dns leading to denial of service
Summary
A flaw was found in Aardvark-dns, which is vulnerable to a Denial of Service attack due to the serial processing of TCP DNS queries. An attacker can exploit this flaw by keeping a TCP connection open indefinitely, causing the server to become unresponsive and resulting in other DNS queries timing out. This issue prevents legitimate users from accessing DNS services, thereby disrupting normal operations and causing service downtime.

Title
Aardvark-dns has incorrect error handling for malformed tcp packets
Summary
Aardvark-dns is an authoritative dns server for A/AAAA container records. From 1.16.0 to 1.17.0, a truncated TCP DNS query followed by a connection reset causes aardvark-dns to enter an unrecoverable infinite error loop at 100% CPU. This vulnerability is fixed in 1.17.1.
Severity ?

Title
Containers/aardvark-dns: tcp query handling flaw in aardvark-dns leading to denial of service
Summary
A flaw was found in Aardvark-dns, which is vulnerable to a Denial of Service attack due to the serial processing of TCP DNS queries. An attacker can exploit this flaw by keeping a TCP connection open indefinitely, causing the server to become unresponsive and resulting in other DNS queries timing out. This issue prevents legitimate users from accessing DNS services, thereby disrupting normal operations and causing service downtime.
