Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user.

The zabbix-agent2 package before 5.4.9-r1 for Alpine Linux sometimes allows privilege escalation to root because the design incorrectly expected that systemd would (in effect) determine part of the configuration.

Alpine Linux version Versions prior to 2.6.10, 2.7.6, and 2.10.1 contains a Other/Unknown vulnerability in apk-tools (Alpine Linux' package manager) that can result in Remote Code Execution. This attack appear to be exploitable via A specially crafted APK-file can cause apk to write arbitrary data to an attacker-specified file, due to bugs in handling long link target name and the way a regular file is extracted.. This vulnerability appears to have been fixed in 2.6.10, 2.7.6, and 2.10.1.

sshd in OpenSSH before 10.6p2 on Linux, when musl libc is used without PAM, lacks a workaround for a password authentication bypass (related to misinterpretation of whether a string is intended to be a password hash). For some configurations of accounts, any password between 256 and 1024 characters succeeds. An example of a platform using musl libc without PAM is Alpine Linux.

A heap overflow in apk (Alpine Linux's package manager) allows a remote attacker to cause a denial of service, or achieve code execution by crafting a malicious APKINDEX.tar.gz file.
