July Patch Tuesday: Large Adobe Security Update and Patches for 18 Critical Microsoft Vulnerabilities

July’s Patch Tuesday addresses 53 vulnerabilities, including 18 critical ones, most of which involve Microsoft’s browsers. These include CVE-2018-8280, CVE-2018-8286, CVE-2018-8290, CVE-2018-8294, and CVE-2018-8298, all of which are corruption bugs in the Chakra Javascript Engine that exist in the way it handles objects in memory in Microsoft Edge. An attacker could then use a specially crafted website that could potentially provide administrative rights to the perpetrator.

CVE-2018-8304, a Windows DNSAPI Denial of Service Vulnerability, is another noteworthy vulnerability addressed this month. An attacker who successfully exploits the vulnerability could cause the shutdown of a DNS server, which could disrupt an organization’s operations. However, this vulnerability does not allow attackers to execute code or change user privileges.

The following vulnerabilities were disclosed via Trend Micro’s Zero Day Initiative (ZDI):

In addition to Microsoft’s regular patch cycle, this month’s Patch Tuesday features a massive round of updates from Adobe addressing 107 vulnerabilities across different Adobe products, including Flash, Reader, Acrobat and Adobe Experience Manager. Of these, 68 came from Trend Micro’s ZDI. CVE-2018-5007, a Flash Player type confusion vulnerability that could lead to remote code execution, is a notable vulnerability patched this month.
