[rbak-nsp] SE100 - BGP Session failure - maybe bug?

[Michael J. Gage]

I have run into this issue with both SE800 & SE400 chassis running various versions of SEOS.
We had to update the SEOS we were running on each of the affected units.

Our two production versions that I know do not have this issue are:
SEOS-6.1.5.7p5-Release (for classic copper cards)
SEOS-11.1.2.5p2-Release (for modern cards)

I do not know which versions are vulnerable and which ones are not between the branches.
I just know that they two we use have this vulnerability fixed.

Hello
since yesterday I have problem with BGP session on SE100.
Log says:

Feb 12 13:34:39: [0001]: %BGP-6-INFO: 111.222.333.444 DOWN - Notification sent
Feb 12 13:34:39: [0001]: %BGP-6-INFO: 111.222.333.444 send NOTIFICATION: 3/5 (update: attribute length error) with 1336 byte data. mxReadMs=24786
BGP session flaps all the time.
I suppose that SE100 receives some attribiute that crashes BGP session down.
Have you met this problem and can you give some hint?
Ahh. SEOS version:
