------

Debian has already patched these in 1.12.1+g01b65bf-3.

Vivid is unaffected as it has the Debian version in which this is fixed. Utopic is known to be affected as it is an affected (and unpatched) 1.12.x version. Trusty is also known to be affected, as it has an affected (and unpatched) version of 1.10.x.

Precise is assumed to be affected, however this is unconfirmed.

------

A debdiff shall be attached to this bug shortly for Utopic.

[Thomas Ward (teward)]

Attached here is a Utopic debdiff to address this issue. The patches are pulled directly from Debian Unstable's 1.12.1+g01b65bf-3 package build. (The only patch not pulled is the GTK crash patch - the scope of nitpicking only covered the security fixes.)

There is a test build here (currently building at the time of this debdiff upload): https://launchpad.net/~teward/+archive/ubuntu/wireshark-security/+packages

[Thomas Ward (teward)]

The Debdiff has been updated to handle a patch that made its way in accidentally. I have removed it from the debdiff. This is building in the PPA as 1.12.1+g01b65bf-2~ubuntu14.10.2.1 because it is necessary to increase the version number so it is accepted/built in the PPA.

ACK on the utopic debdiff, thanks!

[Launchpad Janitor (janitor)]

This bug was fixed in the package wireshark - 1.12.1+g01b65bf-2~ubuntu14.10.2
