Microsoft has rolled out its Patch Tuesday for April to address security issues in Internet Explorer (IE), Edge, ChakraCore, Visual Studio, Microsoft Office and Office Services and Web Apps, and Malware Protection Engine. Of the 67 listed vulnerabilities, 24 were rated critical. Eight of these were disclosed through Trend Micro’s ZDI program:
- CVE-2018-1011
- CVE-2018-1008
- CVE-2018-1004
- CVE-2018-1001
- CVE-2018-1000
- CVE-2018-0996
- CVE-2018-0987
- CVE-2018-0981
While many of Microsoft’s patches for this month are related to information disclosure and memory corruption, the most notable fixes addressed remote code execution (RCE) and security feature bypass vulnerabilities:
- CVE-2018-1010, CVE-2018-1012, CVE-2018-1013, CVE-2018-1015, and CVE-2018-1016 — RCE flaws related to how fonts are handled and rendered. Given the many ways of viewing embedded fonts, they can be ample vectors — from web-based to file-sharing attacks that involve luring an unwitting victim into clicking on an exploit-laden website or document.
- CVE-2018-8117 — a hardware-based security flaw in Microsoft’s Wireless Keyboard 850 that can let hackers repurpose an AES encryption key to read or log keystrokes and send keystrokes to an affected system. This flaw can only be exploited if the attacker is within the keyboard’s wireless range, and after the AES encryption key is extracted.
- CVE-2018-1004 — an RCE flaw in the VBScript engine which, when exploited successfully, can let hackers hijack the vulnerable system and modify or delete its data and programs. A web-based attack entails luring a victim to visit a website via IE that exploits the vulnerability. An attacker can also embed an ActiveX control tagged as “safe for initialization” in an application or document hosting the IE rendering engine.
Microsoft also released an out-of-band update last week for two other vulnerabilities: CVE-2018-1038 (Meltdown), which affects 64-bit Windows 7 and Windows Server 2008; and CVE-2018-0986, an RCE vulnerability involving how Microsoft’s Malware Protection Engine can improperly scan an especially crafted file.
Adobe issued its fixes for 14 vulnerabilities affecting Cold Fusion (APSB18-14), InDesign (APSB18-11), Flash Player (APSB18-08), PhoneGap Push plugin, Digital Editions (APSB18-13), and Experience Manager (APSB18-10). Most of these security flaws are related to information disclosure and RCE.
For the same-origin method execution (SOME) vulnerability (CVE-2018-4943) in PhoneGap Push plugin, Adobe notes that application developers should recompile apps built with PhoneGap after updating.
Apple also rolled out patches for 66 security issues in iOS, watchOS, tvOS, Xcode, iTunes, macOS, iCloud, and Safari. Nine of these vulnerabilities were disclosed via Trend Micro’s ZDI program, and are in WebKit, a component used for displaying web content:
- CVE-2018-4119
- CVE-2018-4122
- CVE-2018-4125
- CVE-2018-4127

- CVE-2018-4130
- CVE-2018-4161
- CVE-2018-4162
- CVE-2018-4163
