According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.26. 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 condition exists in gdImageColorMatch   due to improper calculation of the allocated buffer size. An   unauthenticated, remote attacker can exploit this via calling the   imagecolormatch function with crafted image data as parameters, 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)

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)

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)

ext/imap/php_imap.c in PHP 5.x and 7.x before 7.3.0 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty string in the message argument to the imap_mail function.(CVE-2018-19935)

University of Washington IMAP Toolkit 2007f on UNIX, as used in imap_open() in PHP and other products, launches an rsh command (by means of the imap_rimap function in c-client/imap4r1.c and the tcp_aopen function in osdep/unix/tcp_unix.c) without preventing argument injection, which might allow remote attackers to execute arbitrary OS commands if the IMAP server name is untrusted input (e.g., entered by a user of a web application) and if rsh has been replaced by a program with different argument semantics. For example, if rsh is a link to ssh (as seen on Debian and Ubuntu systems), then the attack can use an IMAP server name containing a '-oProxyCommand' argument.(CVE-2018-19518)

  - Fix php#77020 NULL pointer dereference in imap_mail     CVE-2018-19935

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.39. 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 (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 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)

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.

For Debian 8 'Jessie', these problems have been fixed in version 5.6.39+dfsg-0+deb8u1.

We recommend that you upgrade your php5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple security issues were found in PHP, a widely-used open source general purpose scripting language: The EXIF module was susceptible to denial of service/information disclosure when parsing malformed images, the Apache module allowed cross-site-scripting via the body of a 'Transfer-Encoding: chunked' request and the IMAP extension performed insufficient input validation which can result in the execution of arbitrary shell commands in the imap_open() function and denial of service in the imap_mail() function.

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)
