Description:   Multiple vulnerabilities were reported in Mozilla Thunderbird. A remote user can cause arbitrary code to be executed on the target user's system. A local user can obtain elevated privileges on the target system.

A remote user can create specially crafted content that, when loaded by the target user, will execute arbitrary code on the target system.

Some memory corruption errors may occur [CVE-2015-4473, CVE-2015-4474].

Some memory errors may occur [CVE-2015-4487, CVE-2015-4488, CVE-2015-4489].

On Windows-based systems, a local user can trigger a hardlink race condition to cause the Mozilla Maintenance Service to write its log file to a restricted location with an arbitrary file name. This can be exploited to gain elevated privileges on the target system [CVE-2015-4481].

A remote user can create a MAR file with a specially crafted name that, when opened, will trigger an out-of-bounds write and potentially execute arbitrary code [CVE-2015-4482].

On Linux systems running Gnome, a remote user scale a specially crafted bitmap image to trigger a heap overflow in gdk-pixbuf and potentially execute arbitrary code [CVE-2015-4491].

Gary Kwong, Christian Holler, Byron Campen, Tyson Smith, Bobby Holley, Chris Coulson, Eric Rahm, James Forshaw, Holger Fuhrmannek, Gustavo Grieco, and Ronald Crane reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A local user can obtain elevated privileges on the target system.

Solution:   The vendor has issued a fix (38.2).
