A logic error in vte's OSC parser results in an infinite loop. An untrusted system accessed via ssh, telnet or similar could use this as a denial of service. This is fixed upstream in 0.70.6, and a fixed version 0.70.5-2 is on its way into unstable. Originally reported at <https://bugs.launchpad.net/ubuntu/+source/vte2.91/+bug/2022019>. Does the security team want to do a DSA for this? The patch is upstream commit https://gitlab.gnome.org/GNOME/vte/-/commit/dce7b5f044b0f9e184f186315c846489a20edf0d or one of its many cherry-picks to older branches.
