Oracle Fixes Spectre, Meltdown Flaws With Critical Patch Update

Oracle on Tuesday released its first Critical Patch Update for 2018 to deliver 237 new security fixes across its product portfolio. Over half of the addressed vulnerabilities could be remotely exploited without authentication.

As part of the January 2018 Critical Patch Update, Oracle released fixes for the Critical processor vulnerabilities made public in the beginning of the year, namely Spectre and Meltdown. Impacting modern processors, the bugs put billions of devices at risk, and vendors have been working hard to address them over the past several weeks.

“The January 2018 Critical Patch Update provides fixes for certain Oracle products for the Spectre (CVE-2017-5753, CVE-2017-5715) and Meltdown (CVE-2017-5754) Intel processor vulnerabilities,” Oracle notes in its advisory. Specific details, however, are included in a separate note, accessible only to its customers.

The security updates Oracle released for the Sun Systems Products Suite also include a fix for Oracle X86 Servers to address the CVE-2017-5715 Spectre flaw. The fix “includes Intel microcode that enables OS and VM level mitigations,” but the patch is necessary only for servers using non Oracle OS and Virtualization software.

“Oracle OS and Oracle VM patches for CVE-2017-5715 will include updated Intel microcode,” the company said.

A patch for the same bug was also included in the security updates for Oracle VM VirtualBox.

An article from The Register claims that Oracle admitted in a document on its customer portal that Solaris on SPARCv9 might be impacted by the Spectre flaws. The company reportedly said that patches are being developed, but didn’t provide information on when they would be released or on the performance impact they might have.

The product with the largest number of fixes in the January 2018 Critical Patch Update is Financial Services Applications, at 34 patches. 13 of the flaws could be remotely exploitable without authentication.

Fusion Middleware was the second most impacted Oracle product, at 27 fixes (21 of the bugs being remotely exploitable without authentication), followed by MySQL (25 fixes – 6 remotely exploitable bugs), and Java SE (21 – 18) and Hospitality Applications (21 – 15).

Oracle also resolved bugs in PeopleSoft Products (15 – 8), Supply Chain Products Suite (14 – 12), Virtualization (14 – 3), Sun Systems Products Suite (13 – 7), Retail Applications (11 – 8), Communications Applications (10 – 8), Health Sciences Applications (7 – 5), E-Business Suite (7 – 4), Database Server (5 – 3), Hyperion (4 – 1), Support Tools (3 – 1), JD Edwards Products (2 – 2), Siebel CRM (2 – 0), Construction and Engineering Suite (1 – 0), and Java Micro Edition (1 – 0).

Affecting Apache Log4j, CVE-2017-5645 was the vulnerability with the largest number of occurrences in this set of patches, at 21. It affects Communications Applications, WebLogic Server, PeopleSoft Products, Retail Applications, and Supply Chain Products Suite.

The vulnerability with the highest CVSS score (10) was addressed in Sun ZFS Storage Appliance Kit (AK). The most commonly encountered CVSS score of the addressed vulnerabilities was 9.8. Over 20 such flaws were found in Communications Applications, Fusion Middleware, PeopleSoft, Retail Applications, and Virtualization products.
