session.c in the session extension in PHP before 5.2.13, and 5.3.1, does not properly interpret ; (semicolon) characters in the argument to the sessionsavepath function, which allows context-dependent attackers to bypass openbasedir and safemode restrictions via an argument that contains multiple ; characters in conjunction with a .. (dot dot).
The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as demonstrated by session cookies generated by using the uniqid function.
Use-after-free vulnerability in the request shutdown functionality in PHP 5.2 before 5.2.13 and 5.3 before 5.3.2 allows context-dependent attackers to cause a denial of service (crash) via a stream context structure that is freed before destruction occurs.
The htmlentitydecode function in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allows context-dependent attackers to obtain sensitive information (memory contents) or trigger memory corruption by causing a userspace interruption of an internal call, related to the call time pass by reference feature.
The (1) htmlentities, (2) htmlspecialchars, (3) strgetcsv, (4) httpbuildquery, (5) strpbrk, and (6) strtr functions in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) by causing a userspace interruption of an internal function, related to the call time pass by reference feature.
The (1) iconvmimedecode, (2) iconvsubstr, and (3) iconvmimeencode functions in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 allow context-dependent attackers to obtain sensitive information (memory contents) by causing a userspace interruption of an internal function, related to the call time pass by reference feature.
PHP 5.2.0 and 4.4 allows local users to bypass safemode and openbasedir restrictions via a malicious path and a null byte before a ";" in a sessionsavepath argument, followed by an allowed path, which causes a parsing inconsistency in which PHP validates the allowed path but sets session.savepath to the malicious path.
The unserialize function in PHP 5.3.0 and earlier allows context-dependent attackers to cause a denial of service (resource consumption) via a deeply nested serialized variable, as demonstrated by a string beginning with a:1: followed by many {a:1: sequences.
The zendrestoreinientrycb function in zendini.c in PHP 5.3.0, 5.2.10, and earlier versions allows context-specific attackers to obtain sensitive information (memory contents) and cause a PHP crash by using the iniset function to declare a variable, then using the inirestore function to restore the variable.
PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the fileexists function.
The session extension in PHP before 5.2.4 might allow local users to bypass openbasedir restrictions via a session file that is a symlink.
Buffer overflow in phpwin32std.dll in the win32std extension for PHP 5.2.0 and earlier allows context-dependent attackers to execute arbitrary code via a long string in the filename argument to the winbrowsefile function.
The sessionstart function in ext/session in PHP 4.x up to 4.4.7 and 5.x up to 5.2.3 allows remote attackers to insert arbitrary attributes into the session cookie via special characters in a cookie that is obtained from (1) PATHINFO, (2) the sessionid function, and (3) the sessionstart function, which are not encoded or filtered when the new session cookie is generated, a related issue to CVE-2006-0207.
Multiple integer overflows in the chunksplit 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.
Buffer overflow in the makehttpsoaprequest function in PHP before 5.2.2 has unknown impact and remote attack vectors, possibly related to "/" (slash) characters.
Multiple integer signedness errors in the printf function family in PHP 4 before 4.4.5 and PHP 5 before 5.2.1 on 64 bit machines allow context-dependent attackers to execute arbitrary code via (1) certain negative argument numbers that arise in the phpformattedprint function because of 64 to 32 bit truncation, and bypass a check for the maximum allowable value; and (2) a width and precision of -1, which make it possible for the phpsprintfappendstring function to place an internal buffer at an arbitrary memory location.
CRLF injection vulnerability in the FILTERVALIDATEEMAIL 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.
Buffer overflow in the phpstreamfiltercreate function in PHP 5 before 5.2.1 allows remote attackers to cause a denial of service (application crash) via a php://filter/ URL that has a name ending in the '.' character.
PHP 4 before 4.4.5 and PHP 5 before 5.2.1, when using an empty session save path (session.savepath), uses the TMPDIR default after checking the restrictions, which allows local users to bypass openbasedir restrictions.
The mail function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 truncates e-mail messages at the first ASCIIZ ('\0') byte, which might allow context-dependent attackers to prevent intended information from being delivered in e-mail messages. NOTE: this issue might be security-relevant in cases when the trailing contents of e-mail messages are important, such as logging information or if the message is expected to be well-formed.
