Package: freeradius
Version: 2.1.12+dfsg-1.1
Severity: important

Freeradius can dynamically grow and shrink its thread pool. When
growing the thread pool, multiple threads will call perl_clone
at the same time, which can result in segfaults. The call to
perl_clone should be protected with a mutex.

This was reported in
http://lists.freeradius.org/pipermail/freeradius-devel/2011-November/006568.html
and the patch was integrated for the 2.2.0 release. There hasn't
been a 2.1.x release with this patch yet.

The patch for 2.1.x is here:
