Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
Ulf Harnhammar discovered a remote vulnerability in Lynx when
connecting to a news server (NNTP). The function that added missing
escape chararacters to article headers did not check the size of the
target buffer. Specially crafted news entries could trigger a buffer
overflow, which could be exploited to execute arbitrary code with the
privileges of the user running lynx. In order to exploit this, the
user is not even required to actively visit a news site with Lynx
since a malicious HTML page could automatically redirect to an nntp://
URL with malicious news items.
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 lynx package.
