CVSS: 8.8EPSS: 0%CPEs: 10EXPL: 0CVE-2018-10549 – php: Out-of-bounds read in ext/exif/exif.c:exif_read_data() when reading crafted JPEG data
https://notcve.org/view.php?id=CVE-2018-10549
An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. exif_read_data in ext/exif/exif.c has an out-of-bounds read for crafted JPEG data because exif_iif_add_value mishandles the case of a MakerNote that lacks a final '\0' character. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.36, versiones 7.0.x anteriores a la 7.0.30, versiones 7.1.x anteriores a la 7.1.17 y versiones 7.2.x anteriores a la 7.2.5. exif_read_data en ext/exif/exif.c tiene una lectura fuera de límites para los datos JPEG manipulados debido a que exif_iif_add_value gestiona de manera incorrecta el caso de un MakerNote que carece de un carácter "\0" final. An out-of-bounds read has been found in PHP when function exif_iif_add_value handles the case of a MakerNote that lacks a final terminator character. A remote attacker could use this vulnerability to cause a crash. • http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/104019 http://www.securitytracker.com/id/1040807 https://access.redhat.com/errata/RHSA-2019:2519 https://bugs.php.net/bug.php?id=76130 https://lists.debian.org/debian-lts-announce/2018/06/msg00005.html https://security.gentoo.org/glsa/201812-01 https://security.netapp.com/advisory/ntap-20180607-0003 https://usn.ubuntu.com/3646-1 https://www.debian.org/security/2018 • CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 75%CPEs: 11EXPL: 1CVE-2018-7584 – PHP 7.2.2 - 'php_stream_url_wrap_http_ex' Buffer Overflow
https://notcve.org/view.php?id=CVE-2018-7584
In PHP through 5.6.33, 7.0.x before 7.0.28, 7.1.x through 7.1.14, and 7.2.x through 7.2.2, there is a stack-based buffer under-read while parsing an HTTP response in the php_stream_url_wrap_http_ex function in ext/standard/http_fopen_wrapper.c. This subsequently results in copying a large string. En PHP hasta la versión 5.6.33, versiones 7.0.x anteriores a la 7.0.28, versiones 7.1.x hasta la 7.1.14 y versiones 7.2.x hasta la 7.2.2, hay una sublectura de búfer basada en pila al analizar una respuesta HTTP en la función php_stream_url_wrap_http_ex en ext/standard/http_fopen_wrapper.c. Esto resulta en la copia de una cadena larga. PHP version 7.2.2 contains a memory corruption bug while parsing malformed HTTP response packets. • https://www.exploit-db.com/exploits/44846 http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/103204 http://www.securitytracker.com/id/1041607 https://access.redhat.com/errata/RHSA-2019:2519 https://bugs.php.net/bug.php?id=75981 https://github.com/php/php-src/commit/523f230c831d7b33353203fa34aee4e92ac12bba https://lists.debian.org/debian-lts-announce/2018/03/msg00030.html https://lists.debian.org/debian-lts-announce/2018/06/msg00005.html https://usn.ubuntu.com/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

An issue was discovered in PHP 7.3.x before 7.3.0alpha3, 7.2.x before 7.2.8, and before 7.1.20. The php-fpm master process restarts a child process in an endless loop when using program execution functions (e.g., passthru, exec, shell_exec, or system) with a non-blocking STDIN stream, causing this master process to consume 100% of the CPU, and consume disk space with a large volume of error logs, as demonstrated by an attack by a customer of a shared-hosting facility. Se ha descubierto un problema en PHP en versiones 7.3.x anteriores a la 7.3.0alpha3, versiones 7.2.x anteriores a la 7.2.8 y anteriores a la 7.1.20. El proceso maestro php-fpm reinicia un proceso hijo en un bucle infinito cuando se utilizan funciones de ejecución de programas (por ejemplo, passthru, exec, shell_exec o system) con un flujo non-blocking-STDIN y consumir el espacio del disco con un gran volumen de logs de error, tal y como queda demostrado con un ataque a un cliente de una instalación de alojamiento compartido. • https://bugs.php.net/bug.php?id=70185 https://bugs.php.net/bug.php?id=73342https://github.com/php/php-src/pull/3287 https://bugs.php.net/bug.php?id=75968 https://github.com/php/php-src/blob/PHP-7.1.20/NEWS#L20-L22 https://github.com/php/php-src/commit/69dee5c732fe982c82edb17d0dbc3e79a47748d8 https://usn.ubuntu.com/3766-1 https://usn.ubuntu.com/4279-1 https://www.futureweb.at/security/CVE-2015-9253 • CWE-400: Uncontrolled Resource Consumption •

In PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3, all of the return values of stream_get_meta_data can be controlled if the input can be controlled (e.g., during file uploads). For example, a "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" call mishandles the case where $file is data:text/plain;uri=eviluri, -- in other words, metadata can be set by an attacker. En PHP, en versiones anteriores a la 5.5.32, versiones 5.6.x anteriores a la 5.6.18 y versiones 7.x anteriores a la 7.0.3, todos los valores de retorno de stream_get_meta_data pueden controlarse si se puede controlar la entrada (por ejemplo, durante la subida de archivos). Por ejemplo, una llamada "$uri = stream_get_meta_data(fopen($file, "r"))['uri']" gestiona de manera incorrecta el caso en el que $file es data:text/plain;uri=eviluri, -- en otras palabras, un atacante puede establecer metadatos. • https://bugs.php.net/bug.php?id=71323 https://git.php.net/?p=php-src.git%3Ba=commit%3Bh=6297a117d77fa3a0df2e21ca926a92c231819cd5 https://usn.ubuntu.com/3566-2 https://usn.ubuntu.com/3600-1 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2018-5711
gd_gif_in.c in the GD Graphics Library (aka libgd), as used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before 7.2.1, has an integer signedness error that leads to an infinite loop via a crafted GIF file, as demonstrated by a call to the imagecreatefromgif or imagecreatefromstring PHP function. This is related to GetCode_ and gdImageCreateFromGifCtx. gd_gif_in.c en GD Graphics Library (también conocida como libgd), tal y como se emplea en PHP en versiones anteriores a la 5.6.33, versiones 7.0.x anteriores a la 7.0.27, versiones 7.1.x anteriores a la 7.1.13 y versiones 7.2.x anteriores a la 7.2.1, tiene un error en la propiedad signedness de un número entero que conduce a un bucle infinito mediante un archivo GIF manipulado, tal y como demuestra una llamada a las funciones de PHP imagecreatefromgif o imagecreatefromstring.
