The Zend Engine in PHP 4.x before 4.4.7, and 5.x before 5.2.2, allows remote attackers to cause a denial of service (stack exhaustion and PHP crash) via deeply nested arrays, which trigger deep recursion in the variable destruction routines.

Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded

Multiple integer overflows in the (1) createwbmp and (2) readwbmp functions in wbmp.c in the GD library (libgd) in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allow context-dependent attackers to execute arbitrary code via Wireless Bitmap (WBMP)

The mb_parse_str function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 sets the internal register_globals flag and does not disable it in certain cases when a script terminates, which allows remote attackers to invoke available PHP scripts with

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) s

Unspecified vulnerability in PHP before 5.2.1 allows attackers to "clobber" certain super-global variables via unspecified vectors.

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 in

Integer overflow in PHP 4.4.4 and earlier allows remote context-dependent attackers to execute arbitrary code via a long string to the unserialize function, which triggers the overflow in the ZVAL reference counter.
