The compress.bzip2:// URL wrapper provided by the bz2 extension in PHP before 4.4.7, and 5.x before 5.2.2, does not implement safemode or open_basedir checks, which allows remote attackers to read bzip2 archives located outside of the intended directories.
Buffer overflow in the snmpget function in the snmp extension in PHP 5.2.3 and earlier, including PHP 4.4.6 and probably other PHP 4 versions, allows context-dependent attackers to execute arbitrary code via a long value in the third argument (object id).
Buffer overflow in PHP 4.4.6 and earlier, and unspecified PHP 5 versions, allows local and possibly remote attackers to execute arbitrary code via long server name arguments to the (1) mssql_connect and (2) mssql_pconnect functions.
Integer overflow in the substr_compare function in PHP 5.2.1 and earlier allows context-dependent attackers to read sensitive memory via a large value in the length argument, a different vulnerability than CVE-2006-1991.
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.
Unspecified vulnerabilities in PHP, probably before 5.2.0, allow local users to bypass open_basedir restrictions and perform unspecified actions via unspecified vectors involving the (1) chdir and (2) tempnam functions. NOTE: the tempnam vector might overlap CVE-2006-1494.
Buffer overflow in PHP before 5.2.0 allows remote attackers to execute arbitrary code via crafted UTF-8 inputs to the (1) htmlentities or (2) htmlspecialchars functions.
Race condition in the symlink function in PHP 5.1.6 and earlier allows local users to bypass the open_basedir restriction by using a combination of symlink, mkdir, and unlink functions to change the file path after the open_basedir check and before the file is opened by the underlying system, as demonstrated by symlinking a symlink into a subdirectory, to point to a parent directory via .. (dot dot) sequences, and then unlinking the resulting symlink.
Multiple heap-based buffer overflows in the (1) str_repeat and (2) wordwrap functions in ext/standard/string.c in PHP before 5.1.5, when used on a 64-bit system, have unspecified impact and attack vectors, a different vulnerability than CVE-2006-1990.
