The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2022:0699-1 advisory.

  • The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script’s use of .= with a long string. (CVE-2017-8923)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
