CVSS: 8.8EPSS: 71%CPEs: 12EXPL: 2CVE-2019-6977 – PHP 7.2 - 'imagecolormatch()' Out of Band Heap Write
https://notcve.org/view.php?id=CVE-2019-6977
gdImageColorMatch in gd_color_match.c in the GD Graphics Library (aka LibGD) 2.2.5, as used in the imagecolormatch function in PHP before 5.6.40, 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.1, has a heap-based buffer overflow. This can be exploited by an attacker who is able to trigger imagecolormatch calls with crafted image data. gdImageColorMatch in gd_color_match.c en la versión 2.2.5 de GD Graphics Library (también conocido como LibGD), tal y como se utiliza en la función imagecolormatch en PHP, en versiones anteriores a la 5.6.40, en las 7.x anteriores a la 7.1.26, en las 7.2.x anteriores a la 7.2.14 y en las 7.3.x anteriores a la 7.3.1, tiene un desbordamiento de búfer basado en memoria dinámica (heap). Esto puede ser explotado por un atacante capaz de provocar llamadas imagecolormatch con datos de imagen manipulados. PHP version 7.2 suffers from an imagecolormatch() out-of-band heap write vulnerability. • https://www.exploit-db.com/exploits/46677 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00031.html http://packetstormsecurity.com/files/152459/PHP-7.2-imagecolormatch-Out-Of-Band-Heap-Write.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/106731 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:32 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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. ext/imap/php_imap.c en PHP 5.x y 7.x anteriores a la 7.3.0 permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) mediante una cadena vacía en el argumento del mensaje en la función imap_mail. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html http://www.securityfocus.com/bid/106143 https://bugs.php.net/bug.php?id=77020 https://lists.debian.org/debian-lts-announce/2018/12/msg00006.html https://security.netapp.com/advisory/ntap-20181221-0003 https://www.debian.org/security/2018/dsa-4353 • CWE-476: NULL Pointer Dereference •
CVSS: 8.5EPSS: 96%CPEs: 10EXPL: 7CVE-2018-19518 – PHP imap_open - Remote Code Execution
https://notcve.org/view.php?id=CVE-2018-19518
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. La versión 2007f de University of Washington IMAP Toolkit en UNIX, tal y como se utiliza en imap_open() en PHP y otros productos, lanza un comando rsh (por medio de la función imap_rimap en c-client/imap4r1.c y la función tcp_aopen en osdep/unix/tcp_unix.c) sin prevenir una inyección de argumentos. Esto podría permitir a los atacantes remotos ejecutar comandos arbitrarios del sistema operativo si el nombre del servidor IMAP son entradas no fiables (por ejemplo, si son introducidos por un usuario de una aplicación web) y si rsh ha sido reemplazado por un programa con semánticas de argumentos diversas. Por ejemplo, si rsh es un enlace a ssh (como es el caso de los sistemas Debian y Ubuntu), el ataque puede utilizar un nombre del servidor IMAP que contenga un argumento "-oProxyCommand". • https://www.exploit-db.com/exploits/45914 https://github.com/ensimag-security/CVE-2018-19518 http://www.securityfocus.com/bid/106018 http://www.securitytracker.com/id/1042157 https://antichat.com/threads/463395/#post-4254681 https://bugs.debian.org/913775 https://bugs.debian.org/913835 https://bugs.debian.org/913836 https://bugs.php.net/bug.php?id=76428 https://bugs.php.net/bug.php?id=77153 https://bugs.php.net/bug.php?id=77160 https://git.php.net • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •
CVSS: 6.1EPSS: 0%CPEs: 7EXPL: 1CVE-2018-17082 – php: Cross-site scripting (XSS) flaw in Apache2 component via body of 'Transfer-Encoding: chunked' request
https://notcve.org/view.php?id=CVE-2018-17082
The Apache2 component in PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 allows XSS via the body of a "Transfer-Encoding: chunked" request, because the bucket brigade is mishandled in the php_handler function in sapi/apache2handler/sapi_apache2.c. El componente Apache2 en PHP en versiones anteriores a la 5.6.38, versiones 7.0.x anteriores a la 7.0.32, versiones 7.1.x anteriores a la 7.1.22 y versiones 7.2.x anteriores a la 7.2.10 permite Cross-Site Scripting (XSS) mediante el cuerpo de una petición "Transfer-Encoding: chunked". Esto se debe a que bucket brigade se gestiona de manera incorrecta en la función php_handler en sapi apache2handler sapi_apache2.c. A cross-site scripting (XSS) vulnerability in Apache2 component of PHP was found. When using 'Transfer-Encoding: chunked', the request allows remote attackers to potentially run a malicious script in a victim's browser. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php https://access.redhat.com/errata/RHSA-2019:2519 https://bugs.php.net/bug.php?id=76582 https://github.com/php/php-src/commit/23b057742e3cf199612fa8050ae86cae675e214e https://lists.debian.org/debian-lts-announce/2018/09/msg00020.html https://security.gentoo.org/glsa/201812-01 https://security.netapp.com/advisory/ntap-20180924-0001 https://www.debian.org/security/2018/dsa-4353 https://www.tenable.com/security/tns • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
