Comment 1 Reinhard Max 2022-07-08 12:18:46 UTC
This was apparently already fixed in 2.25, but the respective changelog entry did not explicitly mention STARTTLS, so it went unnoticed:

https://alpineapp.email/alpine/release/alpine-2.25.html

"Bugs that have been addressed include:

  *  The c-client library parses information from an IMAP server during non-authenticated state which could lead to denial of service. Reported by Damian Poddebniak from Münster University of Applied Sciences."

This means we already have fixed packages in Tumbleweed and openSUSE:Backports:SLE-15-SP4:Update, but there are still affected versions in openSUSE:Backports:SLE-15-SP3:Update (2.24) and openSUSE:Backports:SLE-12 (2.20).

Shall we fix these two code streams as well or is it not needed?

we can just do a version update on backports if that stays kind of compatible.
