Update: 20th March 2016:
A more recent blog post provides details of the now released security update.
On Wednesday of last week the anti-malware organization Malwarebytes published a blog post to inform it’s customers that they are working to resolve several security vulnerabilities responsibly disclosed (defined) to them.
The well-known Google security researcher Tavis Ormandy disclosed these issues to them in November 2015. Malwarebytes is currently working to have an updated version of it’s anti-malware product version 2.2.1 available in the next 3 to 4 weeks.
If you are a Malwarebytes business or consumer customer/or make use of their free anti-malware software please monitor the Malwarebytes blog for announcements as well continuing to keep your Malwarebytes product up to date in order to be protected against these security issues. Users of the Premium version of Malwarebytes can enable self-protection in mitigate (protect against) these issues until the appropriate update is made available. Further details of how to enable this security feature are available here.
Malwarebytes also took the opportunity within the above mentioned blog post to announce their Bug Bounty program. This should ensure that such vulnerabilities are disclosed and resolved sooner in the future. Further details of their bug bounty program are available here.
I will update this post when version 2.2.1 of Malwarebytes is made available.
