Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
USN-761-1 fixed vulnerabilities in PHP. This update provides the
corresponding updates for Ubuntu 9.04.
It was discovered that PHP did not sanitize certain error messages
when display_errors is enabled, which could result in browsers
becoming vulnerable to cross-site scripting attacks when processing
the output. With cross-site scripting vulnerabilities, if a user were
tricked into viewing server output during a crafted server request, a
remote attacker could exploit this to modify the contents, or steal
confidential data (such as passwords), within the same domain.
It was discovered that PHP did not properly handle certain
malformed strings when being parsed by the json_decode
function. A remote attacker could exploit this flaw and
cause the PHP server to crash, resulting in a denial of
service. This issue only affected Ubuntu 8.04 and 8.10.
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 packages.
