Descriptions
Integer overflow in the ftp_genlist function in ext/ftp/ftp.c in PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 allows remote FTP servers to execute arbitrary code via a long reply to a LIST command, leading to a heap-based buffer overflow. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-4022.
Desbordamiento de entero en la función ftp_genlist en ext/ftp/ftp.c en PHP en versiones anteriores a 5.4.42, 5.5.x en versiones anteriores a 5.5.26 y 5.6.x en versiones anteriores a 5.6.10 permite a servidores FTP remotos ejecutar código arbitrario a través de una respuesta larga para un comando LIST, encabezando un desbordamiento de buffer basado en memoria dinámica. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2015-4022.
Neal Poole and Tomas Hoger discovered that PHP incorrectly handled NULL bytes in file paths. A remote attacker could possibly use this issue to bypass intended restrictions and create or obtain access to sensitive files. Emmanuel Law discovered that the PHP phar extension incorrectly handled filenames starting with a NULL byte. A remote attacker could use this issue with a crafted tar archive to cause a denial of service. Various other issues were also addressed.
