Based on the work of the Debian community, this patch fixes the
following vulnerability:
This CVE hasn't been addressed upstream and the bugs discussion is 404
[1]. But the same patch is applied on Busybox v1.38 in Yocto & Debian.
- CVE-2024-58251:
In netstat in BusyBox through 1.37.0, local users can launch of
network application with an argv[0] containing an ANSI terminal escape
sequence, leading to a denial of service (terminal locked up) when
netstat is used by a victim.
For more information, see:
- https://salsa.debian.org/installer-team/busybox/-/blob/master/debian/patches/netstat-sanitize-argv0-for-p-CVE-2024-58251.patch
- https://www.cve.org/CVERecord?id=CVE-2024-58251
This patch is still applied on Debian & Yocto as of busybox version
1.38.
