uboot-tools security update
安全等级: High
公告ID: KylinSec-SA-2024-4030
发布日期: 2024年9月27日
关联CVE: CVE-2022-2347
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):
There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer.(CVE-2022-2347)
