GLSA-201611-22

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.26. It is, therefore, affected by multiple vulnerabilities :

 - A flaw exists in ext/standard/var_unserializer.re when destroying deserialized objects due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a deserialize call that references a partially constructed object, to corrupt memory, resulting in a
denial of service condition. (CVE-2016-7411)

 - An heap buffer overflow condition exists in the php_mysqlnd_rowp_read_text_protocol_aux() function within file ext/mysqlnd/mysqlnd_wireprotocol.c due to a failure to verify that a BIT field has the UNSIGNED_FLAG flag. An unauthenticated, remote attacker can exploit this, via specially crafted
field metadata, to cause a denial of service condition. (CVE-2016-7412)

 - A use-after-free error exists in the wddx_stack_destroy() function within file ext/wddx/wddx.c when deserializing recordset elements. An unauthenticated, remote attacker can exploit this, via a specially crafted wddxPacket XML document, to cause a denial of service condition. (CVE-2016-7413)

 - An out-of-bounds access error exists in the phar_parse_zipfile() function within file ext/phar/zip.c due to a failure to ensure that the uncompressed_filesize field is large enough. An unauthenticated, remote attacker can exploit this, via a specially crafted archive, to cause a denial of service
condition. (CVE-2016-7414)

 - A stack-based buffer overflow condition exists in the ICU4C library, specifically within file common/locid.cpp in the msgfmt_format_message() function, due to a failure to properly restrict the locale length provided to the Locale class. An unauthenticated, remote attacker can exploit this, via a
long first argument to a MessageFormatter::formatMessage() function call, to cause a denial of service condition. (CVE-2016-7416)

 - A flaw exists in the spl_array_get_dimension_ptr_ptr() function within file ext/spl/spl_array.c due to a failure to properly validate the return value and data type when deserializing SplArray. An unauthenticated, remote attacker can exploit this, via specially crafted serialized data, to cause a
denial of service condition. (CVE-2016-7417)

 - An out-of-bounds read error exists in the php_wddx_push_element() function within file ext/wddx/wddx.c when handling an incorrect boolean element, which leads to mishandling the wddx_deserialize() call. An unauthenticated, remote attacker can exploit this, via a specially crafted wddxPacket XML
document, to cause a denial of service condition. (CVE-2016-7418)

 - An out-of-bounds access error exists in the phar_parse_tarfile() function within file ext/phar/tar.c when handling the verification of signatures. An unauthenticated, remote attacker can exploit this to cause an unspecified impact.

 - An integer overflow condition exists in the fgetcsv() function when handling CSV field lengths due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code.

 - An integer overflow condition exists in the wordwrap() function within file ext/standard/string.c due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code.

 - An integer overflow condition exists in the fgets() function within file ext/standard/file.c due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code.

 - An integer overflow condition exists in the xml_utf8_encode() function within file ext/xml/xml.c due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to cause an unspecified impact.

 - A flaw exists in the exif_process_IFD_in_TIFF() function within file ext/exif/exif.c when handling uninitialized thumbnail data. An unauthenticated, remote attacker can exploit this to disclose memory contents.

 Note that the scanner has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

CVE-2016-7411 ext/standard/var_unserializer.re in PHP before 5.6.26 mishandles object-deserialization failures, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via an unserialize call that references a partially constructed object.

CVE-2016-7412 ext/mysqlnd/mysqlnd_wireprotocol.c in PHP before 5.6.26 and 7.x before 7.0.11 does not verify that a BIT field has the UNSIGNED_FLAG flag, which allows remote MySQL servers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted field metadata.

CVE-2016-7413 Use-after-free vulnerability in the wddx_stack_destroy function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a wddxPacket XML document that lacks an end-tag for a recordset field element, leading to mishandling in a wddx_deserialize call.

CVE-2016-7414 The ZIP signature-verification feature in PHP before 5.6.26 and 7.x before 7.0.11 does not ensure that the uncompressed_filesize field is large enough, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a crafted PHAR archive, related to ext/phar/util.c and ext/phar/zip.c.

CVE-2016-7416 ext/intl/msgformat/msgformat_format.c in PHP before 5.6.26 and 7.x before 7.0.11 does not properly restrict the locale length provided to the Locale class in the ICU library, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a MessageFormatter::formatMessage call with a long first argument.

CVE-2016-7417 ext/spl/spl_array.c in PHP before 5.6.26 and 7.x before 7.0.11 proceeds with SplArray unserialization without validating a return value and data type, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data.

CVE-2016-7418 The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.26 and 7.x before 7.0.11 allows remote attackers to cause a denial of service (invalid pointer access and out-of-bounds read) or possibly have unspecified other impact via an incorrect boolean element in a wddxPacket XML document, leading to mishandling in a wddx_deserialize call.

For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u6.

We recommend that you upgrade your php5 packages.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

New php packages are available for Slackware 14.0, 14.1, 14.2, and
-current to fix security issues.

Versions of PHP 5.6.x prior to 5.6.26 and 7.0.x prior to 7.0.11 are vulnerable to the following issues :

 - An overflow condition exists in the 'msgfmt_format_message()' function in 'common/locid.cpp' that is triggered when handling local strings. This may allow a remote attacker to cause a stack-based buffer overflow, resulting in a crash or potentially allowing the execution of arbitrary code.
 - An overflow condition exists in the 'php_mysqlnd_rowp_read_text_protocol_aux()' function in 'ext/mysqlnd/mysqlnd_wireprotocol.c' that is triggered when handling the BIT field. This may allow a context-dependent or Man-in-the-Middle (MitM) attacker to cause a heap-based buffer overflow, resulting in a crash or potentially allowing the execution of arbitrary code.
 - A use-after-free error exists in the 'wddx_stack_destroy()' function in 'ext/wddx/wddx.c' that is triggered when deserializing 'recordset' elements. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - An out-of-bounds access flaw exists in the 'phar_parse_zipfile()' function in 'ext/phar/zip.c' that is triggered when handling the uncompressed file size. This may allow a remote attacker to have an unspecified impact.
 - A flaw exists in the 'spl_array_get_dimension_ptr_ptr()' function in 'ext/spl/spl_array.c' that is triggered as types are not properly checked during the unserialization of 'SplArray'. This may allow a remote attacker to cause a crash or potentially have a more severe, unspecified impact.
 - An out-of-bounds access flaw exists in the 'phar_parse_tarfile()' function in 'ext/phar/tar.c' that is triggered during the verification of signatures. This may allow a remote attacker to have an unspecified impact.
 - A flaw is triggered as certain input is not properly validated when destroying deserialized objects. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code.
 - An out-of-bounds read flaw exists in the 'php_wddx_push_element()' function in 'ext/wddx/wddx.c' that may allow a remote attacker to cause a crash or potentially disclose memory contents.
 - An integer overflow flaw exists in the 'fgetcsv()' function. The issue is triggered as certain input is not properly validated when handling CSV field lengths. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code.
 - An integer overflow flaw exists in the 'wordwrap()' function in 'ext/standard/string.c'. The issue is triggered as certain input is not properly validated. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code.
 - An integer overflow flaw exists in the 'fgets()' function in 'ext/standard/file.c'. The issue is triggered as certain input is not properly validated. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code.
 - An integer overflow condition exists in the 'xml_utf8_encode()' function in 'ext/xml/xml.c'. The issue is triggered as certain input is not properly validated. This may allow a remote attacker to have an unspecified impact.
 - A flaw exists in the 'exif_process_IFD_in_TIFF()' function in 'ext/exif/exif.c' that is triggered during the handling of uninitialized thumbnail data. This may allow a remote attacker to disclose the contents of memory.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.26. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists in ext/standard/var_unserializer.re when     destroying deserialized objects due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this, via a deserialize     call that references a partially constructed object, to     corrupt memory, resulting in a denial of service     condition. (CVE-2016-7411)

  - An heap buffer overflow condition exists in the     php_mysqlnd_rowp_read_text_protocol_aux() function     within file ext/mysqlnd/mysqlnd_wireprotocol.c due to     a failure to verify that a BIT field has the     UNSIGNED_FLAG flag. An unauthenticated, remote attacker     can exploit this, via specially crafted field metadata,     to cause a denial of service condition. (CVE-2016-7412)

  - A use-after-free error exists in the     wddx_stack_destroy() function within file     ext/wddx/wddx.c when deserializing recordset elements.
    An unauthenticated, remote attacker can exploit this,     via a specially crafted wddxPacket XML document, to     cause a denial of service condition. (CVE-2016-7413)

  - An out-of-bounds access error exists in the     phar_parse_zipfile() function within file ext/phar/zip.c     due to a failure to ensure that the     uncompressed_filesize field is large enough. An     unauthenticated, remote attacker can exploit this, via a     specially crafted archive, to cause a denial of service     condition. (CVE-2016-7414)

  - A stack-based buffer overflow condition exists in the     ICU4C library, specifically within file common/locid.cpp     in the msgfmt_format_message() function, due to a     failure to properly restrict the locale length provided     to the Locale class. An unauthenticated, remote attacker     can exploit this, via a long first argument to a     MessageFormatter::formatMessage() function call, to     cause a denial of service condition. (CVE-2016-7416)

  - A flaw exists in the spl_array_get_dimension_ptr_ptr()     function within file ext/spl/spl_array.c due to a     failure to properly validate the return value and data     type when deserializing SplArray. An unauthenticated,     remote attacker can exploit this, via specially crafted     serialized data, to cause a denial of service condition.
    (CVE-2016-7417)

  - An out-of-bounds read error exists in the     php_wddx_push_element() function within file     ext/wddx/wddx.c when handling an incorrect boolean     element, which leads to mishandling the     wddx_deserialize() call. An unauthenticated, remote     attacker can exploit this, via a specially crafted     wddxPacket XML document, to cause a denial of service     condition. (CVE-2016-7418)

  - An out-of-bounds access error exists in the     phar_parse_tarfile() function within file ext/phar/tar.c     when handling the verification of signatures. An     unauthenticated, remote attacker can exploit this to     cause an unspecified impact.

  - An integer overflow condition exists in the fgetcsv()     function when handling CSV field lengths due to improper     validation of certain input. An unauthenticated, remote     attacker can exploit this to corrupt memory, resulting     in a denial of service condition or the execution of     arbitrary code.

  - An integer overflow condition exists in the wordwrap()     function within file ext/standard/string.c due to     improper validation of certain input. An     unauthenticated, remote attacker can exploit this to     corrupt memory, resulting in a denial of service     condition or the execution of arbitrary code.

  - An integer overflow condition exists in the fgets()     function within file ext/standard/file.c due to improper     validation of certain input. An unauthenticated, remote     attacker can exploit this to corrupt memory, resulting     in a denial of service condition or the execution of     arbitrary code.

  - An integer overflow condition exists in the     xml_utf8_encode() function within file ext/xml/xml.c due     to improper validation of certain input. An     unauthenticated, remote attacker can exploit this to     cause an unspecified impact.

  - A flaw exists in the exif_process_IFD_in_TIFF() function     within file ext/exif/exif.c when handling uninitialized     thumbnail data. An unauthenticated, remote attacker can     exploit this to disclose memory contents.
