Package : vinagre
Version : 3.22.0-6+deb10u1
CVE ID :
Debian Bug : 983533

It has been found that the update of freerdp2 (see DLA-3606-1) exposed a
bug in vinagre, which causes crashes and breaks RDP connections with the
symtoms of hangs and black screens.

Note: sha256 is now used instead of sha1 to fingerprint certificates. This will
invalidate all hosts in FreeRDP known_hosts2 file, $HOME/.config/freerdp/known_hosts2.
In case of problems with the connection, try removing that file.

For Debian 10 buster, this problem has been fixed in version
3.22.0-6+deb10u1.

We recommend that you upgrade your vinagre packages.
