Description:
Some vulnerabilities have been reported in Xdg-utils, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to the "xgd-open" and "xdg-email" scripts not correctly sanitising parameters before using them in a sed call. This can be exploited to inject and execute shell commands if e.g. a malicious URL is passed to the affected scripts.
Successful exploitation requires that the scripts are not used in a KDE, Gnome, or XFCE session.
The vulnerabilities are reported in version 1.0.2. Other versions may also be affected.
Solution:
Fixed in the CVS repository:
http://webcvs.freedesktop.org/portlan...scripts/xdg-email?r1=1.36&r2=1.37
http://webcvs.freedesktop.org/portlan.../scripts/xdg-open?r1=1.32&r2=1.33
Provided and/or discovered by:
Reported in a Red Hat bug by Miroslav Lichvar.
