The bzread function in ext/bz2/bz2.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted bz2 archive.

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.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. It is, therefore, affected by multiple vulnerabilities :

 - A man-in-the-middle vulnerability exists, known as 'httpoxy', due to a failure to properly resolve namespace conflicts in accordance with RFC 3875 section 4.1.18. The HTTP_PROXY environment variable is set based on untrusted user data in the 'Proxy' header of HTTP requests. The HTTP_PROXY environment variable is used by some web client libraries to specify a remote proxy server. An unauthenticated, remote attacker can exploit this, via a crafted 'Proxy' header in an HTTP request, to redirect an application's internal HTTP traffic to an arbitrary proxy server where it may be observed or manipulated. (CVE-2016-5385)

 - An overflow condition exists in the php_bz2iop_read() function within file ext/bz2/bz2.c due to improper handling of error conditions. An unauthenticated, remote attacker can exploit this, via a crafted request, to execute arbitrary code. (CVE-2016-5399)

 - A flaw exists in the GD Graphics Library (libgd), specifically in the gdImageScaleTwoPass() function within file gd_interpolation.c, due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-6207)

 - An integer overflow condition exists in the virtual_file_ex() function within file Zend/zend_virtual_cwd.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-6289)

 - A use-after-free error exists within the file ext/session/session.c when handling 'var_hash' destruction. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-6290)

 - An out-of-bounds read error exists in the exif_process_IFD_in_MAKERNOTE() function within file ext/exif/exif.c. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or disclose memory contents. (CVE-2016-6291)

 - A NULL pointer dereference flaw exists in the exif_process_user_comment() function within file ext/exif/exif.c. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-6292)

 - Multiple out-of-bounds read errors exist in the locale_accept_from_http() function within file ext/intl/locale/locale_methods.c. An unauthenticated, remote attacker can exploit these to cause a denial of service condition or disclose memory contents. (CVE-2016-6293, CVE-2016-6294)

 - A use-after-free error exists within file ext/snmp/snmp.c when handling garbage collection during deserialization of user-supplied input. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-6295)

 - A heap-based buffer overflow condition exists in the simplestring_addn() function within file simplestring.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-6296)

 - An integer overflow condition exists in the php_stream_zip_opener() function within file ext/zip/zip_stream.c due to improper validation of user-supplied input when handling zip streams. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-6297)

 - An out-of-bounds read error exists in the GD Graphics Library (libgd), specifically in the gdImageScaleBilinearPalette() function within file gd_interpolation.c, when handling transparent color. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or disclose memory contents.

 - A heap-based buffer overflow condition exists in the mdecrypt_generic() function within file ext/mcrypt/mcrypt.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

 - A flaw exists in the curl_unescape() function within file ext/curl/interface.c when handling string lengths. An unauthenticated, remote attacker can exploit this to cause heap corruption, resulting in a denial of service condition.

 - A heap-based buffer overflow condition exists in the mcrypt_generic() function within file ext/mcrypt/mcrypt.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

 - A NULL write flaw exists in the GD Graphics Library (libgd) in the gdImageColorTransparent() function due to improper handling of negative transparent colors. A remote attacker can exploit this to disclose memory contents.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

 - An overflow condition within the 'mdecrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code.
 - A NULL pointer dereference flaw within the 'exif_process_user_comment()' function inside of 'ext/exif/exif.c' may allow a remote attacker to crash a program using the language. (CVE-2016-6292)
 - A flaw within the 'curl_unescape()' function inside of 'ext/curl/interface.c' is triggered during the handling of string lengths. This may allow a remote attacker to trigger heap corruption and crash a program using the language.
 - An overflow condition within the 'mcrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An integer overflow condition within the 'php_stream_zip_opener()' function inside of 'ext/zip/zip_stream.c' is triggered as user-supplied input is not properly validated when handling zip streams. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6297)
 - An integer overflow condition within the 'virtual_file_ex()' function inside of 'Zend/zend_virtual_cwd.c' is triggered as user-supplied input is not properly validated when handling variables. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6289)
 - An overflow condition within the 'simplestring_addn()' function inside of 'simplestring.c.' is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service in a process linked against the library or potentially allowing the execution of arbitrary code. (CVE-2016-6296)
 - A NULL write flaw within the 'gdImageColorTransparent()' function inside of 'gd.c' is triggered during the handling of negative transparent colors. This may allow a context-dependent attacker to disclose memory.
 - An overflow condition within the 'php_url_prase_ex()' function inside of 'ext/standard/url.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a buffer overflow, potentially resulting in a denial of service in a process utilizing the language. (CVE-2016-6288)

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development.

The vulnerabilities are addressed by upgrading PHP to the new upstream version 5.6.24, which includes additional bug fixes. Please refer to the upstream changelog for more information :

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. It is, therefore, affected by multiple vulnerabilities :

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. An unauthenticated, remote attacker can exploit     this, via a crafted 'Proxy' header in an HTTP request,     to redirect an application's internal HTTP traffic to an     arbitrary proxy server where it may be observed or     manipulated. (CVE-2016-5385)

  - An overflow condition exists in the php_bz2iop_read()     function within file ext/bz2/bz2.c due to improper     handling of error conditions. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary code. (CVE-2016-5399)

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.24. It is, therefore, affected by multiple vulnerabilities :

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. An unauthenticated, remote attacker can exploit     this, via a crafted 'Proxy' header in an HTTP request,     to redirect an application's internal HTTP traffic to an     arbitrary proxy server where it may be observed or     manipulated.
