Package        : atari800
Vulnerability  : buffer overflows
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2004-1076

Adam Zabrocki discovered multiple buffer overflows in atari800, an
Atari emulator.  In order to directly access graphics hardware, one of
the affected programs is installed setuid root.  A local attacker
could exploit this vulnerability to gain root privileges.

For the stable distribution (woody) these problems have been fixed in
version 1.2.2-1woody3.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your atari800 package immediately.
