A vulnerability was discovered and corrected in gnucash:

gnc-test-env in GnuCash 2.3.15 and earlier places a zero-length
directory name in the LD_LIBRARY_PATH, which allows local users to
gain privileges via a Trojan horse shared library in the current
working directory (CVE-2010-3999).

The affected /usr/bin/gnc-test-env file has been removed to mitigate
the CVE-2010-3999 vulnerability as gnc-test-env is only used for
tests and while building gnucash.

Additionally for Mandriva 2010.1 gnucash-2.2.9 was not compatible
with guile. This update adapts gnucash to the new API of guile.
