The CentOS Linux 7.9 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0728 advisory.

    This advisory aggregates security fixes for the php SRPM in CIQ CentOS Bridge 7.9. It addresses 65 CVEs:
    CVE-2023-0568, CVE-2021-21702, CVE-2015-6838, CVE-2019-19204, CVE-2016-6297, and 60 more.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.28. It is, therefore, affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist in spl_array.c,     spl_observer.c, and spl_dllist.c due to improper     sanitization of input to the unserialize() function. An     attacker can exploit these issues, by using a specially     crafted SplDoublyLinkedList, SplArrayObject, or     SplObjectStorage object, to deference freed memory and     thus execute arbitrary code. (CVE-2015-6831)

  - A dangling pointer error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to gain     control over a deallocated pointer and thus execute     arbitrary code. (CVE-2015-6832)

  - A path traversal flaw exists in file phar_object.c due     to improper sanitization of user-supplied input. An     attacker can exploit this to write arbitrary files.
    (CVE-2015-6833)

  - A type confusion flaw exists in the     serialize_function_call() function in soap.c due to     improper validation of input passed via the header     field. A remote attacker can exploit this to execute     arbitrary code. (CVE-2015-6836)

  - Multiple type confusion flaws exist in the _call()     method in file php_http.c when handling calls for     zend_hash_get_current_key or 'Z*'. An attacker can     exploit this to disclose memory contents or crash     an application using PHP. (CVE-2015-8835)

  - The openssl_random_pseudo_bytes() function in file     openssl.c does not generate sufficiently random numbers.
    This allows an attacker to more easily predict the     results, thus allowing further attacks to be carried     out. (CVE-2015-8867)

  - A flaw exists in file zend_exceptions.c due to the     improper use of the function unserialize() during     recursive method calls. A remote attacker can exploit     this to crash an application using PHP. (CVE-2015-8873)

  - A flaw exists in file zend_exceptions.c due to     insufficient type checking by functions unserialize()     and __toString(). A remote attacker can exploit this to     cause a NULL pointer deference or unexpected method     execution, thus causing an application using PHP to     crash. (CVE-2015-8876)

  - An integer truncation flaw exists in the     zend_hash_compare() function in zend_hash.c that is     triggered when comparing arrays. A remote attacker can     exploit this to cause arrays to be improperly matched     during comparison.
    Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.12. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists in file spl_dllist.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to     deference freed memory and thus execute arbitrary code.

  - A use-after-free error exists in file spl_observer.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplObjectStorage object, to deference     freed memory and thus execute arbitrary code.

  - A use-after-free error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplArrayObject object, to deference     freed memory and thus execute arbitrary code.

  - A flaw exists in file zend_exceptions.c due to the     improper use of the function unserialize() during     recursive method calls. A remote attacker can exploit     this to crash an application using PHP.

  - A flaw exists in file zend_exceptions.c due to     insufficient type checking by functions unserialize()     and __toString(). A remote attacker can exploit this to     cause a NULL pointer deference or unexpected method     execution, thus causing an application using PHP to     crash.

  - A path traversal flaw exists in file phar_object.c due     to improper sanitization of user-supplied input. An     attacker can exploit this to write arbitrary files.

  - Multiple type confusion flaws exist in the _call()     method in file php_http.c when handling calls for     zend_hash_get_current_key or 'Z*'. An attacker can     exploit this to disclose memory contents or crash     an application using PHP.

  - A dangling pointer error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to gain     control over a deallocated pointer and thus execute     arbitrary code.

  - A flaw exists in the file gd.c due to the improper     handling of images with large negative coordinates by     the imagefilltoborder() function. An attacker can     exploit this to cause a stack overflow, thus crashing     an application using PHP.

  - A flaw exists in the file php_odbc.c when the     odbc_fetch_array() function handles columns that are     defined as NVARCHAR(MAX). An attacker can exploit this     to crash an application using PHP.

  - The openssl_random_pseudo_bytes() function in file     openssl.c does not generate sufficiently random numbers.
    This allows an attacker to more easily predict the     results, thus allowing further attacks to be carried     out.

  - A user-after-free error exists in the unserialize()     function in spl_observer.c due to improper validation     of user-supplied input. A remote attacker can exploit     this to dereference already freed memory, potentially     resulting in the execution of arbitrary code.

  - A type confusion flaw exists in the     serialize_function_call() function in soap.c due to     improper validation of input passed via the header     field. A remote attacker can exploit this to execute     arbitrary code.

  - A use-after-free error exists in the unserialize()     function in spl_dllist.c that is triggered during the     deserialization of user-supplied input. A remote     attacker can exploit this to dereference already freed     memory, potentially resulting in the execution of     arbitrary code.

  - A user-after-free error exists in the gmp_unserialize()     function in gmp.c due to improper validation of     user-supplied input. A remote attacker can exploit this     to dereference already freed memory, potentially     resulting in the execution of arbitrary code.

  - An integer truncation flaw exists in the     zend_hash_compare() function in zend_hash.c that is     triggered when comparing arrays. A remote attacker can     exploit this to cause arrays to be improperly matched     during comparison.
