CVE-2015-4025

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.

Updated php packages fix security vulnerabilities:

Memory Corruption in phar_parse_tarfile when entry filename starts with null (CVE-2015-4021).

Integer overflow in ftp_genlist() resulting in heap overflow, potentially exploitable by a hostile FTP server (CVE-2015-4022).

PHP Multipart/form-data parsing remote DoS Vulnerability (CVE-2015-4024).

Various functions allow \0 in paths where they shouldn't. In theory, that could lead to security failure for path-based access controls if the user injects a string with \0 in it. These functions include set_include_path(), tempnam(), rmdir(), and readlink() (CVE-2015-4025), as well as pcntl_exec() (CVE-2015-4026).

This update for php5 fixes the following issues:

Security issues fixed:

• CVE-2017-16642: Fix timelib_meridian error that could be used to leak information from the interpreter (bsc#1067441).
• CVE-2017-4025: Fix pathname truncation in set_include_path, tempnam, rmdir, and readlink (bsc#1067090).
• CVE-2017-9228: Fix heap out-of-bounds write that occurs in bitset_set_range() during regex compilation (bsc#1069606).
• CVE-2017-9229: Fix invalid pointer dereference in left_adjust_char_head() (bsc#1069631).

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.

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. (CVE-2015-3411, CVE-2015-3412, CVE-2015-4025, CVE-2015-4026, CVE-2015-4598)

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. (CVE-2015-4021)

Max Spelsberg discovered that PHP incorrectly handled the LIST command when connecting to remote FTP servers. A malicious FTP server could possibly use this issue to execute arbitrary code. (CVE-2015-4022, CVE-2015-4643)

Shusheng Liu discovered that PHP incorrectly handled certain malformed form data. A remote attacker could use this issue with crafted form data to cause CPU consumption, leading to a denial of service. (CVE-2015-4024)

Andrea Palazzo discovered that the PHP Soap client incorrectly validated data types. A remote attacker could use this issue with crafted serialized data to possibly execute arbitrary code. (CVE-2015-4147)

Andrea Palazzo discovered that the PHP Soap client incorrectly validated that the uri property is a string. A remote attacker could use this issue with crafted serialized data to possibly obtain sensitive information. (CVE-2015-4148)

Taoguang Chen discovered that PHP incorrectly validated data types in multiple locations. A remote attacker could possibly use these issues to obtain sensitive information or cause a denial of service. (CVE-2015-4599, CVE-2015-4600, CVE-2015-4601, CVE-2015-4602, CVE-2015-4603)

It was discovered that the PHP Fileinfo component incorrectly handled certain files. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service. This issue only affected Ubuntu 15.04. (CVE-2015-4604, CVE-2015-4605)

It was discovered that PHP incorrectly handled table names in php_pgsql_meta_data. A local attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2015-4644)
