Summary
CVE-2009-3292 php: exif extension: Multiple missing sanity checks inEXIF file processingCVE-2009-3291 php: openssl extension: Incorrect verification of SSLcertificate with NUL in nameCVE-2009-3546 gd: insufficient input validation in _gdGetColors()CVE-2009-4017 PHP: resource exhaustion attack via upload requests withlots of filesCVE-2009-4142 php: htmlspecialchars() insufficient checking of input formulti-byte encodingsMultiple missing input sanitization flaws were discovered in PHP's exifextension. A specially-crafted image file could cause the PHPinterpreter to crash or, possibly, disclose portions of its memory whena 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, wasdiscovered in PHP's gd library. A specially-crafted GD image file couldcause the PHP interpreter to crash or, possibly, execute arbitrary codewhen opened. (CVE-2009-3546)It was discovered that PHP did not limit the maximum number of filesthat can be uploaded in one request. A remote attacker could use thisflaw to instigate a denial of service by causing the PHP interpreter touse lots of system resources dealing with requests containing largeamounts of files to be uploaded. This vulnerability depends on fileuploads 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 beuploaded 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 inX.509 certificates. If an attacker is able to get a carefully-craftedcertificate signed by a trusted Certificate Authority, the attackercould use the certificate during a man-in-the-middle attack andpotentially confuse PHP into accepting it by mistake. (CVE-2009-3291)It was discovered that PHP's htmlspecialchars() function did notproperly recognize partial multi-byte sequences for some multi-byteencodings, sending them to output without them being escaped. Anattacker could use this flaw to perform a cross-site scripting attack.(CVE-2009-4142)After installing the updated packages, the httpd daemon must berestarted for the update to take effect.SL 3.0.xSRPMS:php-4.3.2-54.ent.src.rpmi386:php-4.3.2-54.ent.i386.rpmphp-devel-4.3.2-54.ent.i386.rpmphp-imap-4.3.2-54.ent.i386.rpmphp-ldap-4.3.2-54.ent.i386.rpmphp-mysql-4.3.2-54.ent.i386.rpmphp-odbc-4.3.2-54.ent.i386.rpmphp-pgsql-4.3.2-54.ent.i386.rpmx86_64:php-4.3.2-54.ent.x86_64.rpmphp-devel-4.3.2-54.ent.x86_64.rpmphp-imap-4.3.2-54.ent.x86_64.rpmphp-ldap-4.3.2-54.ent.x86_64.rpmphp-mysql-4.3.2-54.ent.x86_64.rpmphp-odbc-4.3.2-54.ent.x86_64.rpmphp-pgsql-4.3.2-54.ent.x86_64.rpm
