    UBUNTU-CVE-2017-17520

    Published: 14 Dec 2017Last Modified: 14 Dec 2017

    Summary:

    Details: ** DISPUTED ** tools/url_handler.pl in TIN 2.4.1 does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL. NOTE: a third party has reported that this is intentional behavior, because the documentation states "url_handler.pl was designed to work together with tin which only issues shell escaped absolute URLs."
