Ubuntu 4.10 / 5.04 : zlib vulnerability (USN-148-1)

high Nessus Plugin ID 20543

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Solution

Update the affected zlib-bin, zlib1g and / or zlib1g-dev packages.
