Hi, thanks for the report. If I've understood the issue correctly
(DoS/crash if malloc fails), it does not look too urgent.

Although the fixes look safe enough, I think we could wait until after
bookworm is released, and fix this in unstable first and in a point
release later. Does that sound OK to you?

thanks,
Ryan

Correct, agreed.

Yes I do agree. The issue can be fixed after the bookworm release for
unstable and trixie, and for bookworm fixing it in the first point
release is absolutely fine. We do not need a DSA here. The same holds
for bullseye.

Thank you for the swift reply back!

Salvatore
