Tavis Ormandy discovered that zlib did not properly verify data
streams. Decompressing certain invalid compressed files caused
corruption of internal data structures, which caused applications
which link to zlib to crash. Specially crafted input might even have
allowed arbitrary code execution.
zlib is used by hundreds of server and client applications, so this
vulnerability could be exploited to cause Denial of Service attacks to
almost all services provided by an Ubuntu system.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected zlib-bin, zlib1g and / or zlib1g-dev packages.
