Ubuntu 4.10 : linux-source- vulnerabilities (USN-47-1)

Ubuntu Security Notice (C) 2004-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

Georgi Guninski discovered two Denial of Service vulnerabilities in
the Linux kernel.

An integer overflow in the vc_resize() function caused the memory
allocation for the new screen being too short, thus causing a buffer
overflow and a kernel crash.

There was also a memory leak in the ip_options_get() function. Calling
ip_cmsg_send() very often would gradually exhaust memory.

Note: The original advisory (see URL above) also mentions a
'ip_options_get integer overflow'. This was already fixed in USN-38-1
(known as CAN-2004-1016).

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 packages.

Risk factor :

Low / CVSS Base Score : 2.1
