April 2020 and – rest assured – your Windows PC can still be pwned by something so innocuous as an unruly font

Adobe and Intel add their woes


Microsoft has delivered another epic Patch Tuesday, dropping fixes for more than 100 security bugs, and Adobe and Intel have added their dose of misery and security too.

April showers from Redmond

The April edition of Patch Tuesday sees the release of fixes for 113 CVE-listed bugs. Four really important ones are already being exploited in the wild. Of those, two target font code ,another goes for an old VBScript error and the last one requires local access.

"In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website," Microsoft warns.

"An attacker could also embed an ActiveX control marked 'safe for initialization' in an application or Microsoft Office document that hosts the IE rendering engine."

A fifth flaw, (CVE-2020-0935) was publicly disclosed but not exploited in the wild. That flaw was an elevation of privilege bug in OneDrive.

The massive patch load is no accident, say experts.

"If you feel like there have been a lot of patches this year, you’re not wrong," notes Dustin Childs of the Trend Micro Zero Day Initiative. "Microsoft has seen a 44 per cent increase in the number of CVEs patched between January to April of 2020 compared to the same time period in 2019."

As per usual, browser bugs make up most of this month's critical updates. Flaws in Redmond's Media Foundation, Chakra Scripting Engine, and SharePoint account for the lion's share of the critical-rated issues this month.

Of more interest are the critical flaws in Hyper-V (CVE-2020-0910) and VBScript (CVE-2020-0967) that allow remote code execution via a guest account or a VBScript engine code break.

Meanwhile, Adobe skipped updates for Flash this month, opting instead to put out fixes for a local privilege escalation flaw in ColdFusion, an information disclosure hole in After Effects, and an information disclosure flaw in Digital Editions.

Six Intel updates

Over in the realm of Chipzilla, we have six patches for various firmware flaws.

They include escalation of privilege flaws in the NUC firmware, escalation of privilege bugs in the Intel Binary Configuration Tool, escalation of privilege errors in the Modular Server Compute Module , Denial of Service bugs in the Driver and Support Assistant, and elevation of privilege flaw in ProSet/Wireless Wifi, and an escalation of privilege error in the Intel Data Migration Software. ®

    Another terrible launch, but DICE is already working on improvements

    The RPG Greetings, traveller, and welcome back to The Register Plays Games, our monthly gaming column. Since the last edition on New World, we hit level cap and the "endgame". Around this time, item duping exploits became rife and every attempt Amazon Games made to fix it just broke something else. The post-level 60 "watermark" system for gear drops is also infuriating and tedious, but not something we were able to address in the column. So bear these things in mind if you were ever tempted. On that note, it's time to look at another newly released shit show – Battlefield 2042.

    I wanted to love Battlefield 2042, I really did. After the bum note of the first-person shooter (FPS) franchise's return to Second World War theatres with Battlefield V (2018), I stupidly assumed the next entry from EA-owned Swedish developer DICE would be a return to form. I was wrong.

    The multiplayer military FPS market is dominated by two forces: Activision's Call of Duty (COD) series and EA's Battlefield. Fans of each franchise are loyal to the point of zealotry with little crossover between player bases. Here's where I stand: COD jumped the shark with Modern Warfare 2 in 2009. It's flip-flopped from WW2 to present-day combat and back again, tried sci-fi, and even the Battle Royale trend with the free-to-play Call of Duty: Warzone (2020), which has been thoroughly ruined by hackers and developer inaction.

  • American diplomats' iPhones reportedly compromised by NSO Group intrusion software

    Reuters claims nine State Department employees outside the US had their devices hacked

    The Apple iPhones of at least nine US State Department officials were compromised by an unidentified entity using NSO Group's Pegasus spyware, according to a report published Friday by Reuters.

    NSO Group in an email to The Register said it has blocked an unnamed customers' access to its system upon receiving an inquiry about the incident but has yet to confirm whether its software was involved.

    "Once the inquiry was received, and before any investigation under our compliance policy, we have decided to immediately terminate relevant customers’ access to the system, due to the severity of the allegations," an NSO spokesperson told The Register in an email. "To this point, we haven’t received any information nor the phone numbers, nor any indication that NSO’s tools were used in this case."

  • Utility biz Delta-Montrose Electric Association loses billing capability and two decades of records after cyber attack

    A US utility company based in Colorado was hit by a ransomware attack in November that wiped out two decades' worth of records and knocked out billing systems that won't be restored until next week at the earliest.

    The attack was detailed by the Delta-Montrose Electric Association (DMEA) in a post on its website explaining that current customers won't be penalised for being unable to pay their bills because of the incident.

    "We are a victim of a malicious cyber security attack. In the middle of an investigation, that is as far as I’m willing to go," DMEA chief exec Alyssa Clemsen Roberts told a public board meeting, as reported by a local paper.
