PHP 5 before 5.2.3 does not enforce the open_basedir or safe_mode restriction in certain cases, which allows context-dependent attackers to determine the existence of arbitrary files by checking if the readfile function returns a string. NOTE: this issue might also involve the realpath function.Show less

Multiple integer overflows in the chunk_split function in PHP 5 before 5.2.3 and PHP 4 before 4.4.8 allow remote attackers to cause a denial of service (crash) or execute arbitrary code via the (1) chunks, (2) srclen, and (3) chunklen arguments.Show less

PHP 4.x and 5.x before 5.2.1, when running on multi-threaded systems, does not ensure thread safety for libc crypt function calls using protection schemes such as a mutex, which creates race conditions that allow remote attackers to overwrite internal program memory and gain system access.Show less

The fopen function in PHP 5.2.0 does not properly handle invalid URI handlers, which allows context-dependent attackers to bypass safe_mode restrictions and read arbitrary files via a file path specified with an invalid URI, as demonstrated via the srpath URI.Show less

The soap extension in PHP calls php_rand_r with an uninitialized seed variable, which has unknown impact and attack vectors, a related issue to the mcrypt_create_iv issue covered by CVE-2007-2727. Note: The PHP team argue that this is not a valid security issue.Show less

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.Show less

CRLF injection vulnerability in the FILTER_VALIDATE_EMAIL filter in ext/filter in PHP 5.2.0 and 5.2.1 allows context-dependent attackers to inject arbitrary e-mail headers via an e-mail address with a '\n' character, which causes a regular expression to ignore the subsequent part of the address string.Show less

Integer overflow in the msg_receive function in PHP 4 before 4.4.5 and PHP 5 before 5.2.1, on FreeBSD and possibly other platforms, allows context-dependent attackers to execute arbitrary code via certain maxsize values, as demonstrated by 0xffffffff.Show less

Integer signedness error in the _zend_mm_alloc_int function in the Zend Memory Manager in PHP 5.2.0 allows remote attackers to execute arbitrary code via a large emalloc request, related to an incorrect signed long cast, as demonstrated via the HTTP SOAP client in PHP, and via a call to msg_receive with the largest positive integer value of maxsize.Show less

Buffer overflow in the sqlite_decode_binary function in src/encode.c in SQLite 2, as used by PHP 4.x through 5.x and other applications, allows context-dependent attackers to execute arbitrary code via an empty value of the in parameter. NOTE: some PHP installations use a bundled version of sqlite without this vulnerability. The SQLite developer has argued that this issue could be due to a misuse of the sqlite_decode_binary() API.Show less

Buffer overflow in the sqlite_decode_binary function in the bundled sqlite library in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via an empty value of the in parameter, as demonstrated by calling the sqlite_udf_decode_binary function with a 0x01 character.Show less

Integer overflow in the str_replace function in PHP 4.4.5 and PHP 5.2.1 allows context-dependent attackers to have an unknown impact via a single character search string in conjunction with a single character replacement string, which causes an "off by one overflow."Show less

Integer overflow in the str_replace function in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 allows context-dependent attackers to execute arbitrary code via a single character search string in conjunction with a long replacement string, which overflows a 32 bit length counter. NOTE: this is probably the same issue as CVE-2007-0906.6.Show less
