Resolve vulnerability: CVE-2021-36159 in apk-tools-2.12.5-r1

Description:

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.

  • Severity: critical
  • Confidence: unknown

Solution:

Upgrade apk-tools to 2.12.6-r0
