Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that mod_proxy_http did not properly handle a large
amount of streamed data when used as a reverse proxy. A remote
attacker could exploit this and cause a denial of service via memory
resource consumption. This issue affected Ubuntu 8.04 LTS, 8.10 and
9.04. (CVE-2009-1890)

It was discovered that mod_deflate did not abort compressing large
files when the connection was closed. A remote attacker could exploit
this and cause a denial of service via CPU resource consumption.
(CVE-2009-1891).

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.
