More than 10 million users of the popular Cyanogen build of Android are exposed to man-in-the-middle attacks thanks to reuse of vulnerable sample code. The zero day vulnerability makes it possible to target any browser used on the popular Android distribution.

A security researcher who works for a top-tier vendor, but asked Vulture South not to use his name, said Cyanogenmod developers among many others had taken Oracle's sample code for Java 1.5 for parsing certificates to obtain hostnames - which is vulnerable to an older bug - and implemented it. Cyanogenmod developers have been contacted about the flaw.
