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

Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

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

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.
(CVE-2008-5814)

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).

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
