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

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