==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 15.04

Summary:

sosreport could be made to expose sensitive information or overwrite files
as the administrator.

Software Description:
- sosreport: Set of tools to gather troubleshooting data from a system

Details:

Dolev Farhi discovered an information disclosure issue in SoS. If the
/etc/fstab file contained passwords, the passwords were included in the
SoS report. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-3925)

Mateusz Guzik discovered that SoS incorrectly handled temporary files. A
local attacker could possibly use this issue to overwrite arbitrary files
or gain access to temporary file contents containing sensitive system
information. (CVE-2015-7529)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
