ID CVE-2007-2727
Summary The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys.

    description Numerous vulnerabilities were discovered in the PHP scripting language that are corrected with this update. An integer overflow in the substr_compare() function allows context-dependent attackers to read sensitive memory via a large value in the length argument. This only affects PHP5 (CVE-2007-1375). A stack-based buffer overflow in the zip:// URI wrapper in PECL ZIP 1.8.3 and earlier allowes remote attackers to execute arbitrary code via a long zip:// URL. This only affects Corporate Server 4.0 (CVE-2007-1399). A CRLF injection vulnerability in the FILTER_VALIDATE_EMAIL filter could allow an attacker to inject arbitrary email headers via a special email address. This only affects Mandriva Linux 2007.1 (CVE-2007-1900). The mcrypt_create_iv() function calls php_rand_r() with an uninitialized seed variable, thus always generating the same initialization vector, which may allow an attacker to decrypt certain data more easily because of the guessable encryption keys (CVE-2007-2727). The soap extension calls php_rand_r() with an uninitialized seec variable, which has unknown impact and attack vectors; an issue similar to that affecting mcrypt_create_iv(). This only affects PHP5 (CVE-2007-2728). The substr_count() function allows attackers to obtain sensitive information via unspecified vectors. This only affects PHP5 (CVE-2007-2748). An infinite loop was found in the gd extension that could be used to cause a denial of service if a script were forced to process certain PNG images from untrusted sources (CVE-2007-2756). An integer overflow flaw was found in the chunk_split() function that ould possibly execute arbitrary code as the apache user if a remote attacker was able to pass arbitrary data to the third argument of chunk_split() (CVE-2007-2872). A flaw in the PHP session cookie handling could allow an attacker to create a cross-site cookie insertion attack if a victim followed an untrusted carefully-crafted URL (CVE-2007-3799). Various integer overflow flaws were discovered in the PHP gd extension that could allow a remote attacker to execute arbitrary code as the apache user (CVE-2007-3996). A flaw in the wordwrap() frunction could result in a denial of ervice if a remote attacker was able to pass arbitrary data to the function (CVE-2007-3998). A flaw in the money_format() function could result in an information leak or denial of service if a remote attacker was able to pass arbitrary data to this function; this situation would be unlikely however (CVE-2007-4658). A bug in the PHP session cookie handling could allow an attacker to stop a victim from viewing a vulnerable website if the victim first visited a malicious website under the control of the attacker who was able to use that page to set a cookie for the vulnerable website (CVE-2007-4670). Updated packages have been patched to prevent these issues. In addition, PECL ZIP version 1.8.10 is being provided for Corporate Server 4.0.
