CVSS: 5.3EPSS: 1%CPEs: 41EXPL: 1CVE-2015-3412 – php: missing null byte checks for paths in various PHP extensions
https://notcve.org/view.php?id=CVE-2015-3412
PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read arbitrary files via crafted input to an application that calls the stream_resolve_include_path function in ext/standard/streamsfuncs.c, as demonstrated by a filename\0.extension attack that bypasses an intended configuration in which client users may read files with only one specific extension. PHP en versiones anteriores a 5.5.40, 5.5.x en versiones anteriores a 5.5.24 y 5.6.x en versiones anteriores a 5.6.8 no asegura que los nombres de ruta carezcan de secuencia %00, lo que permite a atacantes remotos leer archivos arbitrarios a través de una entrada manipulada que llama a la función stream_resolve_include_path en ext/standard/streamsfuncs.c, como se demuestra con un ataque filename\0.extension que eluce una configuración deseada en la que los usuarios cliente pueden leer archivos con sólo una extensión específica. It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=4435b9142ff9813845d5c97ab29a5d637bedb257 http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1135.html http://rhn.redhat.com/errata/RHSA-2015-1186.html http://rhn.redhat.com/errata/RHSA-2015-1187.html http://rhn.redhat.com/errata/RHSA-2015-1218.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityfocus.com/bid/75250 http://www.securitytracker.com/id/1032709 ht • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-254: 7PK - Security Features CWE-626: Null Byte Interaction Error (Poison Null Byte) •
CVSS: 5.1EPSS: 74%CPEs: 61EXPL: 1CVE-2015-4021 – php: memory corruption in phar_parse_tarfile caused by empty entry file name
https://notcve.org/view.php?id=CVE-2015-4021
The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive. La función phar_parse_tarfile en ext/phar/tar.c en PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 no verifica que el primer caracter de un nombre de fichero es diferente al caracter \0, lo que permite a atacantes remotos causar una denegación de servicio (desbordamientos de enteros y corrupción de memoria) a través de una entrada manipulada en un archivo tar. An integer underflow flaw leading to out-of-bounds memory access was found in the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash or, possibly, execute arbitrary code when opened. • http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158616.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158915.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/159031.html http://lists.opensuse.org/opensuse-updates/2015-06/msg00002.html http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1135.html http://rhn.redhat.com/errata/RHSA-2015&# • CWE-189: Numeric Errors CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-4022
Integer overflow in the ftp_genlist function in ext/ftp/ftp.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 allows remote FTP servers to execute arbitrary code via a long reply to a LIST command, leading to a heap-based buffer overflow. Desbordamiento de enteros en la función ftp_genlist en ext/ftp/ftp.c en PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 permite a servidores FTP remotos ejecutar código arbitrario a través de una contestación larga a un comando LIST, que conduce a un desbordamiento de buffer basado en memoria dinámica. An integer overflow flaw leading to a heap-based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code. • http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158616.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158915.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/159031.html http://lists.opensuse.org/opensuse-updates/2015-06/msg00002.html http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1135.html http://rhn.redhat.com/errata/RHSA-2015&# • CWE-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •

Algorithmic complexity vulnerability in the multipart_buffer_headers function in main/rfc1867.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 allows remote attackers to cause a denial of service (CPU consumption) via crafted form data that triggers an improper order-of-growth outcome.

PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 truncates a pathname upon encountering a \x00 character in certain situations, which allows remote attackers to bypass intended extension restrictions and access files or directories with unexpected names via a crafted argument to (1) set_include_path, (2) tempnam, (3) rmdir, or (4) readlink. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243. PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 trunca un nombre de ruta al encontrar un caracter \x00 en ciertas situaciones, lo que permite a atacantes remotos evadir la restricciones de extensión y acceder a ficheros o directorios con nombres no esperados a través de un argumento manipulado en (1) set_include_path, (2) tempnam, (3) rmdir, o (4) readlink. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2006-7243.
