http://security.gentoo.org/

Severity:	high
Title:	Konsole: Code execution
Date:	06/15/2025
Bugs:	#957792
ID:	202506-13

Synopsis

An input sanitization flaw in Konsole might allow remote attackers to execute commands via a malicious URL

Background

Konsole is KDE's terminal emulator.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-apps/konsole	< 24.12.3-r1	>= 24.12.3-r1	All supported architectures

Description

Konsole supports loading URLs from the scheme handlers such as telnet://URL. This can be executed regardless of whether the telnet binary is available. It would fallback to bash in that case and execute arbitrary code.

Impact

Clicking a malicious URL in a browser may lead to arbitrary code execution. Please review the referenced CVE identifier for details.

Workaround

There is no known workaround at this time.

Resolution

All Konsole users should upgrade to the latest version:

          # emerge --sync
          # emerge --ask --oneshot --verbose ">=kde-apps/konsole-24.12.3-r1"
