CVSS: 9.8EPSS: 1%CPEs: 10EXPL: 7CVE-2019-9023 – php: Heap-based buffer over-read in mbstring regular expression functions
https://notcve.org/view.php?id=CVE-2019-9023
An issue was discovered 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. A number of heap-based buffer over-read instances are present in mbstring regular expression functions when supplied with invalid multibyte data. These occur in ext/mbstring/oniguruma/regcomp.c, ext/mbstring/oniguruma/regexec.c, ext/mbstring/oniguruma/regparse.c, ext/mbstring/oniguruma/enc/unicode.c, and ext/mbstring/oniguruma/src/utf32_be.c when a multibyte regular expression pattern contains invalid multibyte sequences. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.40, versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.1. Existen instancias de sobrelectura de búfer basada en memoria dinámica (heap) en las funciones de expresión regular mbstring cuando se les proporcionan datos multibyte inválidos. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html 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/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77370 https://bugs. • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2019-9024
An issue was discovered 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. xmlrpc_decode() can allow a hostile XMLRPC server to cause PHP to read memory outside of allocated areas in base64_decode_xmlrpc in ext/xmlrpc/libxmlrpc/base64.c. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.40, versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.1. xmlrpc_decode() puede permitir que un servidor XMLRPC hostil provoque que la memoria PHP lea memoria más allá de las áreas asignadas en base64_decode_xmlrpc en ext/xmlrpc/libxmlrpc/base64.c. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html 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/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77380 https://security& • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 57%CPEs: 9EXPL: 1CVE-2019-9022 – php: memcpy with negative length via crafted DNS response
https://notcve.org/view.php?id=CVE-2019-9022
An issue was discovered in PHP 7.x before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before 7.3.2. dns_get_record misparses a DNS response, which can allow a hostile DNS server to cause PHP to misuse memcpy, leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries. Se ha descubierto un problema en PHP, en versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.2. dns_get_record analiza erróneamente una respuesta DNS, lo que podría permitir que un servidor DNS hostil provoque que PHP emplee memcpy de forma incorrecta, lo que conduce a que las operaciones de lectura sobrepasen el búfer asignado para los datos DNS. Esto afecta a php_parserr en ext/standard/dns.c para las consultas DNS_CAA y DNS_ANY. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00044.html https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php.net/bug.php?id=77369 https://lists.debian.org/debian-lts-announce/2019/03/msg00043.html https://security.netapp.com/advisory/ntap-20190321-0001 https://usn.ubuntu.com/3902-1 https://usn.ubuntu.com/3922-2 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 9.8EPSS: 2%CPEs: 10EXPL: 1CVE-2019-9021 – php: Heap-based buffer over-read in PHAR reading functions
https://notcve.org/view.php?id=CVE-2019-9021
An issue was discovered 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. A heap-based buffer over-read in PHAR reading functions in the PHAR extension may allow an attacker to read allocated or unallocated memory past the actual data when trying to parse the file name, a different vulnerability than CVE-2018-20783. This is related to phar_detect_phar_fname_ext in ext/phar/phar.c. Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.40, versiones 7.x anteriores a la 7.1.26, versiones 7.2.x anteriores a la 7.2.14 y versiones 7.3.x anteriores a la 7.3.1. Una sobrelectura de búfer basada en memoria dinámica (heap) en las funciones de lectura PHAR en la extensión PHAR podría permitir que un atacante lea memoria asignada o no asignada más allá de los datos reales al intentar analizar el nombre de archivo. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00083.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00104.html 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/106747 http://www.securityfocus.com/bid/107156 https://access.redhat.com/errata/RHSA-2019:2519 https://access.redhat.com/errata/RHSA-2019:3299 https://bugs.php&# • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •

An issue was discovered 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. Invalid input to the function xmlrpc_decode() can lead to an invalid memory access (heap out of bounds read or read after free). This is related to xml_elem_parse_buf in ext/xmlrpc/libxmlrpc/xml_element.c.
