The phar_parse_metadata function in ext/phar/phar.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to cause a denial of service (heap metadata corruption) or possibly have unspecified other impact via a crafted tar archive.

The sqlite3VdbeExec function in vdbe.c in SQLite before 3.8.9 does not properly implement comparison operators, which allows context-dependent attackers to cause a denial of service (invalid free operation) or possibly have unspecified other impact via a crafted CHECK clause, as demonstrated by CHECK(0&O>O) in a CREATE TABLE statement.

The sqlite3VXPrintf function in printf.c in SQLite before 3.8.9 does not properly handle precision and width values during floating-point conversions, which allows context-dependent attackers to cause a denial of service (integer overflow and stack-based buffer overflow) or possibly have unspecified other impact via large integers in a crafted printf function call in a SELECT statement.

Buffer overflow in the intT1_EnvGetCompletePath function in lib/t1lib/t1env.c in t1lib 5.1.1 allows context-dependent attackers to execute arbitrary code via a long FileName parameter. NOTE: this issue was originally reported to be in the imagepsloadfont function in php_gd2.dll in the gd (PHP_GD2) extension in PHP 5.2.3.

Unknown vulnerability in CGI module for PHP 4.3.0 allows attackers to access arbitrary files as the PHP user, and possibly execute PHP code, by bypassing the CGI force redirect settings (cgi.force_redirect or --enable-force-cgi-redirect).

Buffer underflow in the PHP_FILTER_TRIM_DEFAULT macro in the filtering extension (ext/filter) in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by calling filter_var with certain modes such as FILTER_VALIDATE_INT, which causes filter to write a null byte in whitespace that precedes the buffer.

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.

Integer overflow in the zip_read_entry function in PHP 4 before 4.4.5 allows remote attackers to execute arbitrary code via a ZIP archive that contains an entry with a length value of 0xffffffff, which is incremented before use in an emalloc call, triggering a heap overflow.

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.

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.

The shmop functions in PHP before 4.4.5, and before 5.2.1 in the 5.x series, do not verify that their arguments correspond to a shmop resource, which allows context-dependent attackers to read and write arbitrary memory locations via arguments associated with an inappropriate resource, as demonstrated by a GD Image resource.

The session extension in PHP 4 before 4.4.5, and PHP 5 before 5.2.1, calculates the reference count for the session variables without considering the internal pointer from the session globals, which allows context-dependent attackers to execute arbitrary code via a crafted string in the session_register after unsetting HTTP_SESSION_VARS and _SESSION, which destroys the session data Hashtable.

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.

Multiple buffer overflows in PHP before 5.2.1 allow attackers to cause a denial of service and possibly execute arbitrary code via unspecified vectors in the (1) session, (2) zip, (3) imap, and (4) sqlite extensions; (5) stream filters; and the (6) str_replace, (7) mail, (8) ibase_delete_user, (9) ibase_add_user, and (10) ibase_modify_user functions. NOTE: vector 6 might actually be an integer overflow (CVE-2007-1885). NOTE: as of 20070411, vector (3) might involve the imap_mail_compose function (CVE-2007-1825).

Use-after-free vulnerability in the process_nested_data function in ext/standard/var_unserializer.re in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allows remote attackers to execute arbitrary code via a crafted unserialize call that leverages improper handling of duplicate numerical keys within the serialized properties of an object. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-8142.

PHP remote file inclusion vulnerability in usercp_menu.php in AR Memberscript allows remote attackers to execute arbitrary PHP code via a URL in the script_folder parameter.

PHP remote file inclusion vulnerability in signer/final.php in warez distributions of Animated Smiley Generator allows remote attackers to execute arbitrary PHP code via a URL in the smiley parameter. NOTE: the vendor disputes this issue, stating that only Warez versions of Animated Smiley Generator were affected, not the developer-provided software: "Legitimately purchased applications do not allow this exploit.

sapi/cgi/cgi_main.c in the CGI component in PHP through 5.4.36, 5.5.x through 5.5.20, and 5.6.x through 5.6.4, when mmap is used to read a .php file, does not properly consider the mapping's length during processing of an invalid file that begins with a # character and lacks a newline character, which causes an out-of-bounds read and might (1) allow remote attackers to obtain sensitive information from php-cgi process memory by leveraging the ability to upload a .php file or (2) trigger unexpected code execution if a valid PHP script is present in memory locations adjacent to the mapping.

The apprentice_load function in libmagic/apprentice.c in the Fileinfo component in PHP through 5.6.4 attempts to perform a free operation on a stack-based character array, which allows remote attackers to cause a denial of service (memory corruption or application crash) or possibly have unspecified other impact via unknown vectors. NOTE: this is disputed by the vendor because the standard erealloc behavior makes the free operation unreachable
