Adobe issues a second unscheduled update this month to address a bug with a publicly available proof-of-concept code in the wild.

The two vulnerabilities are critical remote code execution flaws that exist in Adobe Photoshop CC.

The recently-patched flaw could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.

The tricky Cortana flaw, CVE-2018-8253, was addressed by Microsoft during Patch Tuesday.

Microsoft rolled out 60 patches for its Patch Tuesday release, impacting 19 critical flaws and 39 important flaws.

Adobe’s August Patch Tuesday release impacts Flash Player, and Acrobat DC and Reader.

The company issued fixes for 112 vulnerabilities in products spanning from Flash Player, Acrobat and Reader, Experience Manager, to Adobe Connect.

One of the most serious issues is a critical remote code execution vulnerability in the Windows DNS, which could allow an attacker to take full control of the targeted machine.

Adobe has issued a round of higher priority patches less than a week after its Patch Tuesday updates last week.

In total, Microsoft’s May Patch Tuesday roundup included 68 security patches, with 21 listed as critical, 45 rated important and two listed low in severity.
