Summary

uboot-tools security update

Details

This package includes the mkimage program, which allows generation of U-Boot images in various formats, and the fw_printenv and fw_setenv programs to read and modify U-Boot's environment.

Security Fix(es):

squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.(CVE-2022-33967)

Severity

6.6 (Medium)
