Ubuntu 6.06 LTS / 8.04 LTS / 8.10 : php5 vulnerabilities (USN-761-1)

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

Description :

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 the
mbstring.func_overload setting within .htaccess files when using
virtual hosts. A virtual host administrator could use this flaw to
cause settings to be applied to other virtual hosts on the same
server. (CVE-2009-0754)

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. (CVE-2009-1271).

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 :

Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 4.3
Public Exploit Available : true
