Synopsis
An application installed on the remote host is affected by multiple vulnerabilities.Description
According to its banner, the version of PHP running on the remote web server is 7.2.x prior to 7.2.14. It is, therefore, affected by multiple vulnerabilities:- An integer underflow condition exists in _gdContributionsAlloc function in gd_interpolation.c. An unauthenticated, remote attacker can have unspecified impact via vectors related to decrementing the u variable. (CVE-2016-10166)
- A denial of service (DoS) vulnerability exists in ext/imap/php_imap.c. An unauthenticated, remote attacker can exploit this issue, via an empty string in the message argument to the imap_mail function, to cause the application to stop responding. (CVE-2018-19935)
- A heap-based buffer overflow exists in gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka LibGD) 2.2.5.
An unauthenticated, remote attacker can exploit this via the triggering of imagecolormatch calls with crafted image data, to cause a denial of service condition or the execution of arbitrary code. (CVE-2019-6977)
- A heap-based buffer over-read exists in the xmlrpc_decode function due to improper validation of input data. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a heap out-of-bounds read or read-after-free condition, which could result in a complete system compromise. (CVE-2019-9020)
- A heap-based buffer over-read exists in the PHAR reading functions in the PHAR extension, due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this, via persuading a user to parse a specially crafted file name on the targeted system, to disclose sensitive information. (CVE-2019-9021)
- An information disclosure vulnerability exists in the dns_get_record function due to improper parsing of DNS responses. An unauthenticated, remote attacker can exploit this, via a specially crafted DNS reply sent from a rogue DNS server to disclose potentially sensitive information. (CVE-2019-9022)
- Multiple heap-based buffer over-read instances exist in mbstring regular expression functions due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this by sending a specially crafted regular expression that contains multibyte sequences, to cause a condition that could allow the attacker to completely compromise the target system. (CVE-2019-9023)
- An out-of-bounds read error exists in the xmlrpc_decode function due to improper implementation of memory operations. An unauthenticated, remote attacker can exploit this, via a hostile XMLRPC server to cause PHP to read from memory outside of allocated areas. (CVE-2019-9024)
