This issue was found by Alpine:
https://gitlab.alpinelinux.org/alpine/aports/-/issues/13661

Details and the patches they used are in the report above, but the
patches are not yet merged upstream, might be worth to wait until
that's fixed since the impact is rather low.

Cheers,

Um, going to that link results in the (closed) alpine bug from three
weeks ago:

"netstat is vulnerable to escape sequence injection (busybox)"

"Alpine ships BusyBox with the netstat applet enabled. This is
vulnerable to escape sequence injection when used from an VT
compatible terminal. To exploit this vulnerability the PTR for a
remote host must contain a escape sequence and the victim has to
execute netstat. I've set up an example at [elided] with the PTR
resolving to \027[33\;46mlocalhost."

The string "e2fsprogs" appears nowhere in on the page.

I've done a search on Alpine/aports looking for "e2fsprogs" and could
only find:

e2fsprogs can be uninstalled manually on systems that depend on it

modloop verification fails with apline usb drive when local disk partition has a alpine installation
#11136 · created 2 years ago by nico

Neither seems to be security related.  Are you sure this was correctly
filed against e2fsprogs?

and I must have mis-pasted the wrong Emacs buffer into the report.

The correct references are
https://bugzilla.redhat.com/show_bug.cgi?id=2069726
https://bugzilla.redhat.com/show_bug.cgi?id=2068113

And the proposed patch was already posted at:
https://lore.kernel.org/linux-ext4/20220421173148.20193-1-lczerner@redhat.com/T/#u

Hi,

Theodore, btw the BTS reference for the e2fsprogs issue is #1010263
and the CVE id CVE-2022-1304.

#1010264 and CVE-2022-28391 is respectively for busybox. the bug
already reassigned accordingly earlier.

Yes, I've noted that already.

Apologies, I didn't get an e-mail notification for the bug getting
reassigned; I should have double checked the BTS web page for the bug
before replying.

Regards,
