https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234103 Bug ID: 234103 Summary: x11/terminology: CVE-2018-20167 Incorrect escaping of crafted files results in code execution Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: enlightenment@FreeBSD.org Reporter: cem@freebsd.org Flags: maintainer-feedback?(enlightenment@FreeBSD.org) Assignee: enlightenment@FreeBSD.org (Copied from Redhat bugzilla.) Terminology before 1.3.1 allows Remote Code Execution because popmedia is mishandled, as demonstrated by an unsafe "cat README.md" command when \e}pn= is used. A popmedia control sequence can allow the malicious execution of executable file formats registered in the X desktop share MIME types (/usr/share/applications). The control sequence defers unknown file types to the handle_unknown_media() function, which executes xdg-open against the filename specified in the sequence. The use of xdg-open for all unknown file types allows executable file formats with a registered shared MIME type to = be executed. An attacker can achieve remote code execution by introducing an executable file and a plain text file containing the control sequence throu= gh a fake software project (e.g., in Git or a tarball). When the control sequenc= e is rendered (such as with cat), the executable file will be run. https://www.enlightenment.org/news/2018-12-16-terminology-1.3.1 https://phab.enlightenment.org/T7504 https://phab.enlightenment.org/rTRM1ac204da9148e7bccb1b5f34b523e2094dfc39e2 --=20 You are receiving this mail because: You are the assignee for the bug.=
