Description

Trustwave SpiderLabs has reported a vulnerability in Vino, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the "vino_server_client_data_pending()" function (server/vino-server.c), which can be exploited to trigger an infinite 
loop via specially crafted packets.

The vulnerability is reported in versions prior to 3.9.92.


Solution:
Update to version 3.9.92 or later.

Provided and/or discovered by:
Robert Foggia, TrustWave SpiderLabs.

@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.

+  Fix DoS vulnerability and remove vulnerable version (CVE-2013-5745, bug
+  #486694, thanks to Agostino Sarubbo).

Thanks, this had already been fixed in 3.8.1-r1, and I've now added 2.32.2-r2 to use the same patch.

=net-misc/vino-2.32.2-r2 should be stabilized.

CVE-2013-5745 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-5745):
  The vino_server_client_data_pending function in vino-server.c in GNOME Vino
  2.26.1, 2.32.1, 3.7.3, and earlier, and 3.8 when encryption is disabled,
  does not properly clear client data when an error causes the connection to
  close during authentication, which allows remote attackers to cause a denial
  of service (infinite loop, CPU and disk consumption) via multiple crafted
  requests during authentication.
