Gentoo: GLSA-202506-13 high: Konsole remote command execution
gentoo
June 15, 2025
An input sanitization flaw in Konsole might allow remote attackers to execute commands via a malicious URL
Summary
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.
Topics Covered
Resolution
All Konsole users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-apps/konsole-24.12.3-r1"
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-apps/konsole-24.12.3-r1"
