Ubuntu 4.10 : linux-source-2.6.8.1 vulnerabilities (USN-47-1)

Ubuntu Security Notice (C) 2004-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

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

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).

Solution :

Update the affected packages.

Risk factor :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:N/I:N/A:P)
