Synopsis:	Moderate: php security update
Issue date:	2010-01-13
CVE Names:	CVE-2009-2687 CVE-2009-3291 CVE-2009-3292
 CVE-2009-3546 CVE-2009-4017 CVE-2009-4142

CVE-2009-2687 php: exif_read_data crash on corrupted JPEG files
CVE-2009-3292 php: exif extension: Multiple missing sanity checks in
EXIF file processing
CVE-2009-3291 php: openssl extension: Incorrect verification of SSL
certificate with NUL in name
CVE-2009-3546 gd: insufficient input validation in _gdGetColors()
CVE-2009-4017 PHP: resource exhaustion attack via upload requests with
lots of files
CVE-2009-4142 php: htmlspecialchars() insufficient checking of input for
multi-byte encodings

Multiple missing input sanitization flaws were discovered in PHP's exif
extension. A specially-crafted image file could cause the PHP
interpreter to crash or, possibly, disclose portions of its memory when
a PHP script tried to extract Exchangeable image file format (Exif)
metadata from the image file. (CVE-2009-2687, CVE-2009-3292)

A missing input sanitization flaw, leading to a buffer overflow, was
discovered in PHP's gd library. A specially-crafted GD image file could
cause the PHP interpreter to crash or, possibly, execute arbitrary code
when opened. (CVE-2009-3546)

It was discovered that PHP did not limit the maximum number of files
that can be uploaded in one request. A remote attacker could use this
flaw to instigate a denial of service by causing the PHP interpreter to
use lots of system resources dealing with requests containing large
amounts of files to be uploaded. This vulnerability depends on file
uploads being enabled (which it is, in the default PHP configuration).
(CVE-2009-4017)

Note: This update introduces a new configuration option,
max_file_uploads, used for limiting the number of files that can be
uploaded in one request. By default, the limit is 20 files per request.

It was discovered that PHP was affected by the previously published
"null prefix attack", caused by incorrect handling of NUL characters in
X.509 certificates. If an attacker is able to get a carefully-crafted
certificate signed by a trusted Certificate Authority, the attacker
could use the certificate during a man-in-the-middle attack and
potentially confuse PHP into accepting it by mistake. (CVE-2009-3291)

It was discovered that PHP's htmlspecialchars() function did not
properly recognize partial multi-byte sequences for some multi-byte
encodings, sending them to output without them being escaped. An
attacker could use this flaw to perform a cross-site scripting attack.
(CVE-2009-4142)

After installing the updated packages, the httpd daemon must be
restarted for the update to take effect.
