Synopsis: Moderate: php security update Issue date: 2007-09-26 CVE Names: CVE-2007-2509 CVE-2007-2756 CVE-2007-2872 CVE-2007-3799 CVE-2007-3996 CVE-2007-3998 CVE-2007-4658 CVE-2007-4670 Various integer overflow flaws were found in the PHP gd extension script that could be forced to resize images from an untrusted source, possibly allowing a remote attacker to execute arbitrary code as the apache user. (CVE-2007-3996) An integer overflow flaw was found in the PHP chunk_split function. If a remote attacker was able to pass arbitrary data to the third argument of chunk_split they could possibly execute arbitrary code as the apache user. Note that it is unusual for a PHP script to use the chunk_split function with a user-supplied third argument. (CVE-2007-2872) A previous security update introduced a bug into PHP session cookie handling. This could allow an attacker to stop a victim from viewing a vulnerable web site if the victim has first visited a malicious web page under the control of the attacker, and that page can set a cookie for the vulnerable web site. (CVE-2007-4670) A flaw was found in the PHP money_format function. If a remote attacker was able to pass arbitrary data to the money_format function this could possibly result in an information leak or denial of service. Note that it is unusual for a PHP script to pass user-supplied data to the money_format function. (CVE-2007-4658) A flaw was found in the PHP wordwrap function. If a remote attacker was able to pass arbitrary data to the wordwrap function this could possibly result in a denial of service. (CVE-2007-3998) A bug was found in PHP session cookie handling. This could allow an attacker to create a cross-site cookie insertion attack if a victim follows an untrusted carefully-crafted URL. (CVE-2007-3799) An infinite-loop flaw was discovered in the PHP gd extension. A script that could be forced to process PNG images from an untrusted source could allow a remote attacker to cause a denial of service. (CVE-2007-2756) A flaw was found in the PHP "ftp" extension. If a PHP script used this extension to provide access to a private FTP server, and passed untrusted script input directly to any function provided by this extension, a remote attacker would be able to send arbitrary FTP commands to the server.
