Hi,
I'd like to update asterisk with a fix for two minor CVEs that have been deemed
no-dsa. Exactly the same change (apart from the d/gbp.conf update for the
Buster branch) has been uploaded to sid as -2 and migrated to testing a month
ago.
Debdiff attached.
Bernhard

+Subject: [PATCH] chan_sip: Handle invalid SDP answer to T.38 re-invite
+
+The chan_sip module performs a T.38 re-invite using a single media
+stream of udptl, and expects the SDP answer to be the same.
+
+If an SDP answer is received instead that contains an additional
+media stream with no joint codec a crash will occur as the code
+assumes that at least one joint codec will exist in this
+scenario.
+
+This change removes this assumption.
