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)

description	Vulnerabilities have been discovered in php5, a server-side, HTML-embedded scripting language. Note that this update includes a change to the default behavior for IMAP connections. See below for details. CVE-2018-19518 An argument injection vulnerability in imap_open() may allow a remote attacker to execute arbitrary OS commands on the IMAP server. The fix for the CVE-2018-19518 vulnerability included this additional note from the upstream developers : Starting with 5.6.38, rsh/ssh logins are disabled by default. Use imap.enable_insecure_rsh if you want to enable them. Note that the IMAP library does not filter mailbox names before passing them to rsh/ssh command, thus passing untrusted data to this function with rsh/ssh enabled is insecure. CVE-2018-19935 A NULL pointer dereference leads to an application crash and a denial of service via an empty string in the message argument to the imap_mail function of ext/imap/php_imap.c.

description	According to its banner, the version of PHP running on the remote web server is 7.3.0 [alpha\|beta] prior to 7.3.0. It is, therefore, affected by multiple vulnerabilities: - An arbitrary command injection vulnerability exists in the imap_open function due to improper filters for mailbox names prior to passing them to rsh or ssh commands. An authenticated, remote attacker can exploit this by sending a specially crafted IMAP server name to cause the execution of arbitrary commands on the target system. (CVE-2018-19518) - A denial of service vulnerability exists in the imap_mail function due to improper data validation. An unauthenticated, remote attacker can exploit this 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 buffer over-read exists in the phar_parse_pharfile function. An unauthenticated, remote attacker can exploit this to read allocated or unallocated memory past the actual data when trying to parse a .phar file. (CVE-2018-20783)
