The sapi_header_op function in main/SAPI.c in PHP before 5.4.38, 5.5.x before 5.5.22, and 5.6.x before 5.6.6 supports deprecated line folding without considering browser compatibility, which allows remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer by leveraging (1) %0A%20 or (2) %0D%0A%20 mishandling in the header function.

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.

This update for php5 fixes the following issues :

  - It is possible to launch a web server with 'php -S     localhost:8080' It used to be possible to set an     arbitrary $HTTP_PROXY environment variable for request     handlers -- like CGI scripts -- by including a specially     crafted HTTP header in the request (CVE-2016-5385). As a     result, these server components would potentially direct     all their outgoing HTTP traffic through a malicious     proxy server. This patch fixes the issue: the updated     php server ignores such HTTP headers and never sets     $HTTP_PROXY for sub-processes. (bnc#988486)

  - There was multiple cases where a remote attacker could     trigger a double free and, given specific PHP code using     callbacks, trigger code execution vectors.
    (bnc#986246,bnc#986244,CVE-2016-5768,CVE-2016-5772)

  - It was possible to inject header or content information     (XSS) when a user was using internet explorer as the     browser. (bnc#986004, CVE-2015-8935)

  - In several cases it was possible for a integer overflow     to trigger an excessive memory allocation (bnc#986392,     bnc#986388, bnc#986386, bnc#986393, CVE-2016-5770,     CVE-2016-5769, CVE-2016-5766, CVE-2016-5767)

  - It was possible for an attacker to abuse the garbage     collector to free a target array. At this point an     attacker could craft a fake zval object and exploit the     PHP process by taking over the EIP/RIP. (bnc#986391,     CVE-2016-5771)

 - A flaw exists in 'main/php_open_temporary_file.c' that is triggered as thread safety is not ensured during the handling of temporary directories. This may allow a remote attacker to cause a denial of service. (CVE-2015-8878)
 - An integer overflow flaw exists in the 'php_html_entities()' and 'php_filter_full_special_chars()' functions in 'ext/standard/html.c' that is triggered as input is not properly validated. This may allow a remote attacker to have an unspecified impact. No further details have been provided. (CVE-2016-5094, CVE-2016-5095)
 - An integer underflow issue exists in 'ext/standard/file.c' that is triggered as input is not properly validated. This may allow a remote attacker to cause a NULL write and cause a process linked against PHP to crash. (CVE-2016-5096)
 - An out-of-bounds read flaw exists in the '_gdContributionsCalc()' function in 'ext/gd/libgd/gd_interpolation.c'. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents. (CVE-2013-7456)
 - An out-of-bounds read flaw exists in the 'get_icu_value_internal()' function within 'ext/intl/locale/locale_methods.c' that is triggered when handling user-supplied input. This may allow a remote attacker to crash a process linked against the library or potentially disclose memory contents. (CVE-2016-5093)
 - A flaw exists that allows a cross-site scripting (XSS) attack. This flaw exists because the 'header()' function does not filter input passed via HTTP headers before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2015-8935)
 - A use-after-free error exists in the garbage collection algorithm in 'ext/zip/php_zip.c'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-5773)
 - An integer overflow condition exists in the 'json_decode()' and 'json_utf8_to_utf16()' functions in 'ext/standard/php_smart_str.h'. The issue is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, causing a denial of service in a process linked against PHP or potentially allowing the execution of arbitrary code.
 - An out-of-bounds read flaw exists within the 'pass2_no_dither()' function inside 'ext/gd/libgd/gd_topal.c' that may allow a remote attacker to crash a process utilizing PHP or potentially disclose memory contents.
 - An integer overflow condition exists in 'ext/standard/string.c'. The issue is triggered as user-supplied input is not properly validated when handling string lengths. This may allow a remote attacker to have an unspecified impact.
