Who isn't patching?!
The Register explains:
Patching rates went down in 2016 despite an increase in availability of security patches, according to a new study out today.
Last year Secunia Research at Flexera Software recorded a total of 17,147 vulnerabilities in 2,136 products from 246 vendors.
Even though a big majority (81 per cent) of all vulnerabilities had patches on the day of disclosure there was a decrease in patching rates. This is a clear indicator that the software supply chain is broken, according to security researchers.
The rate of unpatched PDF Readers is very high, according to Secunia. Three in four (75 per cent) of its private users ran unpatched versions of Adobe Reader in 2016, despite a plethora of available patches.
