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.

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.
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.
PHP before 5.2.5 allows local users to bypass protection mechanisms configured through phpadminvalue or phpadminflag in httpd.conf by using iniset to modify arbitrary configuration variables, a different issue than CVE-2006-4625.
The (1) htmlentities and (2) htmlspecialchars functions in PHP before 5.2.5 accept partial multibyte sequences, which has unknown impact and attack vectors, a different issue than CVE-2006-5465.
The outputaddrewritevar function in PHP before 5.2.5 rewrites local forms in which the ACTION attribute references a non-local URL, which allows remote attackers to obtain potentially sensitive information by reading the requests for this URL, as demonstrated by a rewritten form containing a local session ID.
ioncubeloaderwin5.2.dll in the ionCube Loader 6.5 extension for PHP 5.2.4 does not follow safemode and disablefunctions restrictions, which allows context-dependent attackers to bypass intended limitations, as demonstrated by reading arbitrary files via the ioncubereadfile function.
The dl function in PHP 5.2.4 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in the library parameter. NOTE: there are limited usage scenarios under which this would be a vulnerability.
The MySQL extension in PHP 5.2.4 and earlier allows remote attackers to bypass safemode and openbasedir restrictions via the MySQL (1) LOADFILE, (2) INTO DUMPFILE, and (3) INTO OUTFILE functions, a different issue than CVE-2007-3997.
curl/interface.c in the cURL library (aka libcurl) in PHP 5.2.4 and 5.2.5 allows context-dependent attackers to bypass safemode and openbasedir restrictions and read arbitrary files via a file:// request containing a \x00 sequence, a different vulnerability than CVE-2006-2563.
The iconvsubstr function in PHP 5.2.4 and earlier allows context-dependent attackers to cause (1) a denial of service (application crash) via a long string in the charset parameter, probably also requiring a long string in the str parameter; or (2) a denial of service (temporary application hang) via a long string in the str parameter. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.
PHP 5.2.4 and earlier allows context-dependent attackers to cause a denial of service (application crash) via (1) a long string in the outcharset parameter to the iconv function; or a long string in the charset parameter to the (2) iconvmimedecodeheaders, (3) iconvmimedecode, or (4) iconvstrlen function. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless these issues can be demonstrated for code execution.
