Debian Security Advisory 2281-1
Posted Jul 21, 2011
Authored by Debian | Site debian.org

Debian Linux Security Advisory 2281-1 - Sebastian Krahmer discovered that opie, a system that makes it simple to use One-Time passwords in applications, is prone to a privilege escalation (CVE-2011-2490) and an off-by-one error, which can lead to the execution of arbitrary code (CVE-2011-2489). Adam Zabrocki and Maksymilian Arciemowicz also discovered another off-by-one error (CVE-2010-1938), which only affects the lenny version as the fix was already included for squeeze.
