Oracle is releasing a huge number of security patches to its customers today, addressing flaws in hundreds of its products.

The 59 patches in the “critical patch update” fall across products ranges from the Oracle Database – 13 fixes – Fusion Middleware – seven fixes – Applications – 16 fixes – and Enterprise Manager Grid Control – one fix.

However, the most fixes are for the Solaris product suite, acquired by Oracle when it bought out Sun Microsystems in January this year.

“Seven of these vulnerabilities may be remotely exploitable without authentication, i.e. may be exploited over a network without the need for a username and password,” warned a security advisory from the company.

“Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply Critical Patch Update fixes as soon as possible.”

The large patch by Oracle has filled the whole left by Adobe which would have normally conducted its quarterly patch today. However it had to bring the patch forward to the end of June after critical flaws were found in its Acrobat and Reader products.
