**Nome do software vulnerável e versões afetadas** Alpine Linux apk-tools versões anteriores à 2.12.5 **Descrição** O problema está relacionado a um estouro de buffer no analisador de tarballs, o que pode causar uma falha no sistema. **Recomendações** Para versões anteriores à 2.12.5, atualize para a versão 2.12.5 ou posterior para resolver o problema.

**Name of the Vulnerable Software and Affected Versions** DNRD versions prior to 2.19.1 **Description** A buffer overflow issue exists in the Domain Name Relay Daemon (DNRD) that allows remote attackers to execute arbitrary code. This is achieved by sending a large number of large DNS packets with the Z and QR flags cleared. **Recommendations** For versions prior to 2.19.1, update to version 2.19.1 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Domain Name Relay Daemon (DNRD) versions prior to 2.19.1 **Description** The issue allows remote attackers to cause a denial of service due to infinite recursion. This can be achieved via a DNS packet that utilizes message compression in the QNAME and includes two pointers that point to each other, creating a circular buffer. **Recommendations** For versions prior to 2.19.1, update to version 2.19.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the DNS service to minimize the risk of exploitation.
