Description Mike Frysinger 2005-02-23 00:33:22 EST
just forwarding a bug that we've fixed in Gentoo ...

BZ2_bzclose fails to perform a NULL pointer check before actually
using the passed BZFILE * argument. The NULL check *is* performed but
only after the argument is used for the first time, resulting in a
potential NULL pointer dereference.
