1. This isn't exactly new. It's been possible to do this since the
original days of BGP.
Literally the first thing that came into my mind was the as-set issue
from 2 decades ago where some vendors passed it, others dropped sessions..
2. Probably not wise to assume that's accurate just because he thinks
that is true.

Fair update. To be clear, though, the main point of the article
stands, and is maybe even strengthened by the update. A corrupted
attribute def can cause the behavior (personal experience speaking
here with a different attribute) and vendors should adopt RFC7606
and not be absolutely awful at responding to vulnerability reporting.

The attribute was not malformed.
This is the hex dump of the attribute: “E0 1C 00”
It is described here.
https://www.rfc-editor.org/rfc/rfc6790#section-5.2
This attribute is deprecated, but that does not prevent
routers from originating it or passing it on.
Kind Regards,

Ran across this article today and haven't seen posts about it so i
figured I would share:
https://blog.benjojo.co.uk/post/bgp-path-attributes-grave-error-handling?fbclid=IwAR13ePY43Vf3u4X8PDyCDT39DtyXczAKkv6CGXOQbcQv90Y3aIAmTkJxn7k_aem_Ad0hzj2Mh_WlbFZug-vGdlJJdXr2Xo0RFIsPwAU2GviPz6xZDib76YHwFuzU7E0_sJk&mibextid=Zxz2cZ
Curious if anyone on the list is running VyOS and has
experienced any problems?
Cheers,
Mike
