The second Tuesday of the month has arrived which means the arrival of regularly scheduled patches from Microsoft and other vendors. This month’s release includes sixteen bulletins from Microsoft, as well as an update from Adobe for their PDF-related application. A separate update for Flash Player will arrive later this week.Read More
ImageMagick is a popular software suite that is used to display, convert, and edit images. On May 3, security researchers publicly disclosed multiple vulnerabilities in the open-source image processing tool in this suite, one of which could potentially allow remote attackers to take over websites.Read More
In early April of this year a zero-day exploit (designated as CVE-2016-1019) was found in Adobe Flash Player. This particular flaw was soon used by the Magnitude Exploit Kit, which led to an Adobe out-of-cycle patch. This flaw was being used to lead to drive-by download attacks with Locky ransomware as the payload.
However, this did not end the threat for users. We recently saw a new variant of this attack that added an unusual twist. On top of the Flash exploit, an old escalation of privileges exploit in Windows (CVE-2015-1701) was used to bypass sandbox technologies.Read More
The critical role of patch management comes into play when vulnerabilities are used by attackers as entry points to infiltrate their target systems and networks or when security flaws are abused to spread any threats. The case of the infamous SAMSAM crypto-ransomware supports this. The said threat deviated from other crypto-ransomware families. Instead of arriving via malicious URLs or spam emails, it leverages security flaws in unpatched servers. Last March 2016, SAMSAM hit the Maryland hospital by encrypting all its files, including those found in the network. From the healthcare industry, SAMSAM moves to target the education sector. In a recent attack, a significant number of servers and systems were exposed to SAMSAM and other malware via JBoss server vulnerabilities. JBoss is an open source application server that runs on Java. Systems or servers with ‘Destiny’ software were also affected. According to a report by CISCO, this software is typically used by K-12 schools worldwide. Follett has already released a patch to protect users of Destiny software.Read More
13 security bulletins were released in this month’s Patch Tuesday addressing vulnerabilities in Internet Explorer, Microsoft Edge, Microsoft Office, and Microsoft XML Core Services, among others. Out of these bulletins, six are rated as ‘Critical’ while seven are tagged as ‘Important.’ Both MS16-037 and MS16-038 which fixed vulnerabilities in Internet Explorer and Edge respectively, could allow remote code execution when exploited successfully.
Perhaps, the most notable among the vulnerabilities resolved in this month’s Patch Tuesday is MS16-047, more popularly known as the Badlock vulnerability that has been circulating in the last few weeks. With all the hype, this vulnerability, which affects all Windows systems and Samba servers, only received an ‘Important’ rating. One of our researchers wrote a detailed entry debunking the hype surrounding this vulnerability.Read More
