Package: chromium
Version: 43.0.2357.65-1
Severity: serious
Tags: security upstream
Justification: Policy 2.1.2
Control: forwarded -1 https://code.google.com/p/chromium/issues/detail?id=491435

Dear Maintainer,

After upgrading chromium to 43, I noticed that when it is running and
immediately after the machine is on-line it silently starts downloading
"Chrome Hotword Shared Module" extension, which contains a binary without
source code. There seems no opt-out config.

$ chromium --temp-profile &
$ find /tmp/tmp.*/Default/Extensions/lccekmodgklaepjeofjdjpbminllajkg/
$ file /tmp/tmp.YClr3VfmnS/Default/Extensions/lccekmodgklaepjeofjdjpbminllajkg/
/tmp/tmp.YClr3VfmnS/Default/Extensions/lccekmodgklaepjeofjdjpbminllajkg/ ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, BuildID[sha1]=24d25d55886dca48921031d6928b0a34f5659830, stripped
