Description Sandipan Roy 2023-06-14 12:37:21 UTC

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.
