  • sosreport - Set of tools to gather troubleshooting data from a system


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)

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

Ubuntu 15.10
