Fixed bug GHSA-3qgc-jrrr-25jv (Bypass of CVE-2012-1823, Argument Injection in PHP-CGI). (CVE-2024-4577)

Cross-site scripting (XSS) vulnerability in PHP, possibly 5.2.7 and earlier, when displayerrors is enabled, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. NOTE: because of the lack of details, it is unclear whether this is related to CVE-2006-0208.

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.

PHP 5 before 5.2.7 does not enforce the errorlog safemode restrictions when safemode is enabled through a phpadminflag setting in httpd.conf, which allows context-dependent attackers to write to arbitrary files by placing a "phpvalue errorlog" entry in a .htaccess file.

PHP 5 before 5.2.7 does not properly initialize the pageuid and pagegid global variables for use by the SAPI phpgetuid function, which allows context-dependent attackers to bypass safemode restrictions via variable settings that are intended to be restricted to root, as demonstrated by a setting of /etc for the errorlog variable.

Heap-based buffer overflow in ext/mbstring/libmbfl/filters/mbfilterhtmlent.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) mbconvertencoding, (2) mbcheckencoding, (3) mbconvertvariables, and (4) mbparsestr functions.

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 bgdcolor or clrBack argument) for an indexed image.

session.c in the session extension in PHP before 5.2.13, and 5.3.1, does not properly interpret ; (semicolon) characters in the argument to the sessionsavepath function, which allows context-dependent attackers to bypass openbasedir and safemode restrictions via an argument that contains multiple ; characters in conjunction with a .. (dot dot).

Unspecified vulnerabilities in PHP, probably before 5.2.0, allow local users to bypass openbasedir 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 openbasedir restriction by using a combination of symlink, mkdir, and unlink functions to change the file path after the openbasedir 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.

Integer overflow in PHP 5 up to 5.1.6 and 4 before 4.3.0 allows remote attackers to execute arbitrary code via an argument to the unserialize PHP function with a large value for the number of array elements, which triggers the overflow in the Zend Engine ecalloc function (Zend/zendalloc.c).

The unserialize function in PHP 5.3.0 and earlier allows context-dependent attackers to cause a denial of service (resource consumption) via a deeply nested serialized variable, as demonstrated by a string beginning with a:1: followed by many {a:1: sequences.

The zendrestoreinientrycb function in zendini.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 iniset function to declare a variable, then using the inirestore function to restore the variable.

PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the fileexists function.

PHP 4.x up to 4.4.4 and PHP 5 up to 5.1.6 allows local users to bypass certain Apache HTTP Server httpd.conf options, such as safemode and openbasedir, via the inirestore function, which resets the values to their php.ini (Master Value) defaults.

The stripos function in PHP before 5.1.5 has unknown impact and attack vectors related to an out-of-bounds read.

Buffer overflow in the LWZReadByte function in ext/gd/libgd/gdgifin.c in the GD extension in PHP before 5.1.5 allows remote attackers to have an unknown impact via a GIF file with inputcodesize greater than MAXLWZBITS, which triggers an overflow when initializing the table array.

Integer overflow in memory allocation routines in PHP before 5.1.6, when running on a 64-bit system, allows context-dependent attackers to bypass the memorylimit restriction.

The (1) fileexists and (2) imapreopen functions in PHP before 5.1.5 do not check for the safemode and openbasedir settings, which allows local users to bypass the settings. NOTE: the errorlog function is covered by CVE-2006-3011, and the imapopen function is covered by CVE-2006-1017.

PHP before 4.4.3 and 5.x before 5.1.4 does not limit the character set of the session identifier (PHPSESSID) for third party session handlers, which might make it easier for remote attackers to exploit other vulnerabilities by inserting PHP code into the PHPSESSID, which is stored in the session file. NOTE: it could be argued that this not a vulnerability in PHP itself, rather a design limitation that enables certain attacks against session handlers that do not account for this limitation.

scanf.c in PHP 5.1.4 and earlier, and 4.4.3 and earlier, allows context-dependent attackers to execute arbitrary code via a sscanf PHP function call that performs argument swapping, which increments an index past the end of an array and triggers a buffer over-read.

zendhashdelkeyorindex in zendhash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zendhashdel to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.

The errorlog function in basicfunctions.c in PHP before 4.4.4 and 5.x before 5.1.5 allows local users to bypass safe mode and openbasedir restrictions via a "php://" or other scheme in the third argument, which disables safe mode.

The substrcompare function in string.c in PHP 5.1.2 allows context-dependent attackers to cause a denial of service (memory access violation) via an out-of-bounds offset argument.

Integer overflow in the wordwrap function in string.c in PHP 4.4.2 and 5.1.2 might allow context-dependent attackers to execute arbitrary code via certain long arguments that cause a small buffer to be allocated, which triggers a heap-based buffer overflow in a memcpy function call, a different vulnerability than CVE-2002-1396.

The copy function in file.c in PHP 4.4.2 and 5.1.2 allows local users to bypass safe mode and read arbitrary files via a source argument containing a compress.zlib:// URI.

PHP 4.4.2 and 5.1.2 allows local users to cause a crash (segmentation fault) by defining and executing a recursive function. NOTE: it has been reported by a reliable third party that some later versions are also affected.

PHP before 5.1.3-RC1 might allow remote attackers to obtain portions of memory via crafted binary data sent to a script that processes user input in the htmlentitydecode function and sends the encoded results back to the client, aka a "binary safety" issue. NOTE: this issue has been referred to as a "memory leak," but it is an information leak that discloses memory contents.

Directory traversal vulnerability in file.c in PHP 4.4.2 and 5.1.2 allows local users to bypass openbasedir restrictions allows remote attackers to create files in arbitrary directories via the tempnam function.
