Updated terminology package fixes security vulnerability CVE-2018-20167

Publication date: 11 Jan 2019
Type: security
Affected Mageia releases : 6
CVE: CVE-2018-20167

Description

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 through a fake
software project (e.g., in Git or a tarball). When the control sequence
is rendered (such as with cat), the executable file will be run.
