CVSS v3.1 |
| 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. |
| 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. |
| PHP 4 before 4.4.5 and PHP 5 before 5.2.1, when using an empty session save path (session.save_path), uses the TMPDIR default after checking the restrictions, which allows local users to bypass open_basedir restrictions. |
| Buffer underflow in PHP before 5.2.1 allows attackers to cause a denial of service via unspecified vectors involving the sapi_header_op function. |
| PHP before 5.2.1 allows attackers to bypass safe_mode and open_basedir restrictions via unspecified vectors in the session extension. NOTE: it is possible that this issue is a duplicate of CVE-2006-6383. |
| Directory traversal vulnerability in the ZipArchive::extractTo function in PHP 5.2.6 and earlier allows context-dependent attackers to write arbitrary files via a ZIP file with a file whose name contains .. (dot dot) sequences. |
| The imap_body function in PHP before 4.4.4 does not implement safemode or open_basedir checks, which allows local users to read arbitrary files or list arbitrary directory contents. |
| 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:". |
| PHP 5.2.1 allows context-dependent attackers to read portions of heap memory by executing certain scripts with a serialized data input string beginning with S:, which does not properly track the number of input bytes being processed. |
| 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. |
| The ovrimos_longreadlen function in the Ovrimos extension for PHP before 4.4.5 allows context-dependent attackers to write to arbitrary memory locations via the result_id and length arguments. |
| The proc_open function in ext/standard/proc_open.c in PHP before 5.2.11 and 5.3.x before 5.3.1 does not enforce the (1) safe_mode_allowed_env_vars and (2) safe_mode_protected_env_vars directives, which allows context-dependent attackers to execute programs with an arbitrary environment via the env parameter, as demonstrated by a crafted value of the LD_LIBRARY_PATH environment variable. |
| The com_print_typeinfo function in the bz2 extension in PHP 5.2.3 allows context-dependent attackers to cause a denial of service via a long argument. |
| 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. |
| The zend_restore_ini_entry_cb function in zend_ini.c in PHP 5.3.0, 5.2.10, and earlier versions allows context-specific attackers to obtain sensitive information (memory contents) and cause a PHP crash by using the ini_set function to declare a variable, then using the ini_restore function to restore the variable. |
| Array index error in the imageRotate function in PHP 5.2.8 and earlier allows context-dependent attackers to read the contents of arbitrary memory locations via a crafted value of the third argument (aka the bgd_color or clrBack argument) for an indexed image. |
| Multiple directory traversal vulnerabilities in PHP 5.2.6 and earlier allow context-dependent attackers to bypass safe_mode restrictions by creating a subdirectory named http: and then placing ../ (dot dot slash) sequences in an http URL argument to the (1) chdir or (2) ftok function. |
| The zend_alter_ini_entry function in PHP before 5.2.4 does not properly handle an interruption to the flow of execution triggered by a memory_limit violation, which has unknown impact and attack vectors. |
| Heap-based buffer overflow in ext/mbstring/libmbfl/filters/mbfilter_htmlent.c in the mbstring extension in PHP 4.3.0 through 5.2.6 allows context-dependent attackers to execute arbitrary code via a crafted string containing an HTML entity, which is not properly handled during Unicode conversion, related to the (1) mb_convert_encoding, (2) mb_check_encoding, (3) mb_convert_variables, and (4) mb_parse_str functions. |
| Stack-based buffer overflow in the FastCGI SAPI (fastcgi.c) in PHP before 5.2.6 has unknown impact and attack vectors. |
