NVD Description

Note: Versions mentioned in the description apply only to the upstream apk-tools package and not the apk-tools package as distributed by Alpine. See How to fix? for Alpine:3.10 relevant fixed versions and status.

libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. The FTP passive mode implementation allows an out-of-bounds read because strtol is used to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for the '\0' terminator one byte too late.

Remediation

Upgrade Alpine:3.10 apk-tools to version 2.10.7-r0 or higher.
