Integer overflow in the exif_process_IFD_TAG function in exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote attackers to read the contents of arbitrary memory locations or cause a denial of service via a crafted offset_val value in an EXIF header in a JPEG file, a different vulnerability than CVE-2011-0708.
The parse_str function in (1) PHP, (2) Hardened-PHP, and (3) Suhosin, when called without a second parameter, might allow remote attackers to overwrite arbitrary variables by specifying variable names and values in the string to be parsed. NOTE: it is not clear whether this is a design limitation of the function or a bug in PHP, although it is likely to be regarded as a bug in Hardened-PHP and Suhosin.
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.
