CVE-2014-3856

Updated fish packages fix security vulnerability:

fish, from at least version 1.16.0 to version 2.1.0 (inclusive), does not check the credentials of processes communicating over the fishd universal variable server UNIX domain socket. This allows a local attacker to elevate their privileges to those of a target user running fish, including root (CVE-2014-2905).

fish, from at least version 1.16.0 to version 2.1.0 (inclusive), creates temporary files in an insecure manner.

Versions 1.23.0 to 2.1.0 (inclusive) execute code via funced from these temporary files, allowing privilege escalation to those of any user running fish, including root (CVE-2014-3856).

Additionally, from at least version 1.16.0 to version 2.1.0 (inclusive), fish will read data using the psub function from these temporary files, meaning that the input of commands used with the psub function is under the control of the attacker (CVE-2014-2906).

fish, from version 2.0.0 to version 2.1.0 (inclusive), fails to restrict connections to the Web-based configuration service (fish_config). This allows remote attackers to execute arbitrary code in the context of the user running fish_config (CVE-2014-2914).

The service is generally only running for short periods of time. The use of the fish_config tool is optional as other interfaces to fish configuration are available.

The fish package has been updated to version 2.1.1 to fix these issues.

This update supplies the 'fish3' package, complementary to the 'fish' package.

This update includes fish3 into the openSUSE Leap 15.1 distribution.

These are all security issues fixed in the fish-2.4.0-1.1 package on the GA media of openSUSE Tumbleweed.
