Description

This security bulletin contains information about 2 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-6790)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

An issue was discovered in KDE Plasma Workspace before 5.12.0. dataengines/notifications/notificationsengine.cpp allows remote attackers to discover client IP addresses via a URL in a notification, as demonstrated by the src attribute of an IMG element.


2) OS Command Injection (CVE-ID: CVE-2018-6791)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

An issue was discovered in soliduiserver/deviceserviceaction.cpp in KDE Plasma Workspace before 5.12.0. When a vfat thumbdrive that contains `` or $() in its volume label is plugged in and mounted through the device notifier, it's interpreted as a shell command, leading to a possibility of arbitrary command execution. An example of an offending volume label is "$(touch b)" -- this will create a file called b in the home folder.
