DESCRIPTION:
"Overflow.pl" has discovered a security issue in libsafe, which can
be exploited by malicious people to bypass the security mechanism.
The security issue is caused due to a race condition when processing
simultaneous attacks in separated threads. This can be exploited to
bypass the protection mechanism in a multi-threaded application
linked against the vulnerable library.
The security issue has been confirmed in version 2.0-16. Other
versions may also be affected.
SOLUTION:
Don't rely solely on the protection mechanism to prevent exploitation
(especially in multi-threaded applications).
