PHP » PHP : Security Vulnerabilities Published In 2007 (Code Execution)

Directory traversal vulnerability in PHP 5.2.4 and earlier allows attackers to bypass open_basedir restrictions and possibly execute arbitrary code via a .. (dot dot) in the dl function.

The perl extension in PHP does not follow safe_mode restrictions, which allows context-dependent attackers to execute arbitrary code via the Perl eval function. NOTE: this might only be a vulnerability in limited environments.

Multiple buffer overflows in php_iisfunc.dll in the iisfunc extension for PHP 5.2.0 and earlier allow context-dependent attackers to execute arbitrary code, probably during Unicode conversion, as demonstrated by a long string in the first argument to the iis_getservicestate function, related to the ServiceId argument to the (1) fnStartService, (2) fnGetServiceState, (3) fnStopService, and possibly other functions.

The Foreign Function Interface (ffi) extension in PHP 5.0.5 does not follow safe_mode restrictions, which allows context-dependent attackers to execute arbitrary code by loading an arbitrary DLL and calling a function, as demonstrated by kernel32.dll and the WinExec function. NOTE: this issue does not cross privilege boundaries in most contexts, so perhaps it should not be included in CVE.

Multiple buffer overflows in the php_ntuser component for PHP 5.2.3 allow context-dependent attackers to cause a denial of service or execute arbitrary code via long arguments to the (1) ntuser_getuserlist, (2) ntuser_getuserinfo, (3) ntuser_getusergroups, or (4) ntuser_getdomaincontroller functions.

Buffer overflow in php_win32std.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 win_browse_file function.

Buffer overflow in the mSQL extension in PHP 5.2.3 allows context-dependent attackers to execute arbitrary code via a long first argument to the msql_connect function.

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.

Multiple integer overflows in libgd in PHP before 5.2.4 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large (1) srcW or (2) srcH value to the (a) gdImageCopyResized function, or a large (3) sy (height) or (4) sx (width) value to the (b) gdImageCreate or the (c) gdImageCreateTrueColor function.

The glob function in PHP 5.2.3 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via an invalid value of the flags parameter, probably related to memory corruption or an invalid read on win32 platforms, and possibly related to lack of initialization for a glob structure.

Multiple buffer overflows in libtidy, as used in the Tidy extension for PHP 5.2.3 and possibly other products, allow context-dependent attackers to execute arbitrary code via (1) a long second argument to the tidy_parse_string function or (2) an unspecified vector to the tidy_repair_string function. NOTE: this might only be an issue in environments where vsnprintf is implemented as a wrapper for vsprintf.

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.

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.

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.

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.

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.

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 php_formatted_print 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 php_sprintf_appendstring function to place an internal buffer at an arbitrary memory location.

Buffer overflow in the imap_mail_compose function in PHP 5 before 5.2.1, and PHP 4 before 4.4.5, allows remote attackers to execute arbitrary code via a long boundary string in a type.parameters field. NOTE: as of 20070411, it appears that this issue might be subsumed by CVE-2007-0906.3.

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.

Double free vulnerability in the unserializer in PHP 4.4.5 and 4.4.6 allows context-dependent attackers to execute arbitrary code by overwriting variables pointing to (1) the GLOBALS array or (2) the session data in _SESSION. NOTE: this issue was introduced when attempting to patch CVE-2007-1701 (MOPB-31-2007).

Buffer overflow in the confirm_phpdoc_compiled function in the phpDOC extension (PECL phpDOC) in PHP 5.2.1 allows context-dependent attackers to execute arbitrary code via a long argument string.

PHP 4 before 4.4.5, and PHP 5 before 5.2.1, when register_globals is enabled, allows context-dependent attackers to execute arbitrary code via deserialization of session data, which overwrites arbitrary global variables, as demonstrated by calling session_decode on a string beginning with "_SESSION|s:39:".

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 underflow in the header function in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by passing an all-whitespace string to this function, which causes it to write '\0' characters in whitespace that precedes the string.
