The php_wddx_process_data function in ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before 7.0.10 allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via an invalid ISO 8601 time value, as demonstrated by a wddx_deserialize call that mishandles a dateTime element in a wddxPacket XML document.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

  - php: Uninitialized read in exif_process_IFD_in_TIFF (CVE-2019-9641)

  - The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a     valid network IP address, which allows remote attackers to obtain network information and facilitate other     attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0.
    NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way     that is similar to strcpy's role in buffer overflows, in which case this would be a class of     implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a     security-relevant manner. (CVE-2006-4023)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Session fixation vulnerability in the Sessions subsystem in PHP before 5.5.2 allows remote attackers to     hijack web sessions by specifying a session ID. (CVE-2011-4718)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

This update was imported from the SUSE:SLE-12:Update update project.

Versions of PHP 5.6.x prior to 5.6.25 and 7.0.x prior to 7.0.10 are vulnerable to the following issues :

 - An uninitialized memory use flaw exists in the 'openssl_seal()' method. This may allow a remote attacker to potentially execute arbitrary code.
 - A use-after-free error exists in 'SPL_METHOD(SplObjectStorage)' in 'ext/spl/spl_observer.c'. The issue is triggered when handling unserialize calls. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists related to certificate validation in the 'ftp_ssl_connect()' function. The issue is due to the server hostname not being verified to match a domain name in the 'Subject's Common Name' (CN) or 'SubjectAltName' field of the X.509 certificate. By spoofing the TLS/SSL server via a certificate that appears valid, an attacker with the ability to intercept network traffic (e.g. MitM, DNS cache poisoning) can disclose and optionally manipulate transmitted data.
 - An overflow condition exists in the 'curl_escape()' function in 'ext/curl/interface.c' that is triggered when handling overly long strings. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a crash or potentially allowing the execution of arbitrary code.
 - A flaw exists in the 'object_common2()' function in 'ext/standard/var_unserializer.c' that is triggered when handling objects during unserialization. This may allow a remote attacker to potentially execute arbitrary code.
 - An integer overflow condition exists in the 'php_snmp_parse_oid()' function in 'ext/snmp/snmp.c'. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - An integer truncation flaw exists in the 'select_colors()' function in 'ext/gd/libgd/gd_topal.c' that is triggered when handling the number of colors. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'sql_regcase()' function in 'ext/ereg/ereg.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A NULL pointer dereference flaw exists in the 'php_wddx_pop_element()' function in 'ext/wddx/wddx.c' that is triggered during the handling of Base64 binary values. This may allow a remote attacker to cause a denial of service.
 - A NULL pointer dereference flaw exists in the 'php_wddx_pop_element()' function in 'ext/wddx/wddx.c'. This may allow a remote attacker to cause a denial of service.
 - An integer overflow condition exists in the 'php_base64_encode()' function in 'ext/standard/base64.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A NULL pointer dereference flaw exists in the 'php_wddx_deserialize_ex()' function in 'ext/wddx/wddx.c' that is triggered during the handling of invalid XML content. This may allow a remote attacker to cause a denial of service.
 - An integer overflow condition exists in the 'php_quot_print_encode()' function in 'ext/standard/quot_print.c' that is triggered when handling overly long strings. This may allow a remote attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
 - A use-after-free error exists in the 'unserialize()' function in 'ext/standard/var.c'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists in the 'php_ftp_fopen_connect()' function in 'ext/standard/ftp_fopen_wrapper.c' as it may silently downgrade to regular FTP even if a secure method has been requested. This may allow a Man-in-the-Middle (MitM) attacker to downgrade the FTP communication.
 - A flaw exists in the 'php_wddx_process_data()' function in 'ext/wddx/wddx.c' that is triggered when deserializing invalid dateTime values. This may allow a remote attacker to cause a crash.
 - A flaw exists in the 'exif_process_IFD_in_TIFF()' function in 'ext/exif/exif.c' that is triggered when handling TIFF image content. This may allow a remote attacker to disclose memory contents.
 - An integer overflow condition exists in the 'php_url_encode()' function in 'ext/standard/url.c' that is triggered when handling overly long strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'php_uuencode()' function in 'ext/standard/uuencode.c'. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'bzdecompress()' function in 'ext/bz2/bz2.c'. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - An integer overflow condition exists in the 'zend_mm_realloc_heap()' function in 'Zend/zend_alloc.c' that is triggered as certain input is not properly validated. This may allow a remote attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An array indexing flaw exists in the 'imagegammacorrect()' function in 'ext/gd/gd.c' that is triggered when handling negative gamma values. This may allow a remote attacker to write a NULL to an arbitrary memory location, causing a crash or potentially allowing the execution of arbitrary code.
 - An integer overflow condition exists in the 'curl_escape()' function in 'ext/curl/interface.c' that is triggered when handling overly long escaped strings. This may allow a remote attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in 'ext/session/session.c' that is triggered when handling session names. This may allow a remote attacker to inject arbitrary data into sessions.
