"The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in
the ELSA-2015-1219 advisory.

  - 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. (CVE-2015-4021)

  - 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. (CVE-2015-4022)

  - 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.
    (CVE-2015-4024)

  - 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. (CVE-2015-4025)

  - The pcntl_exec implementation in 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, which might allow remote attackers to bypass intended
    extension restrictions and execute files with unexpected names via a crafted first argument. NOTE: this
    vulnerability exists because of an incomplete fix for CVE-2006-7243. (CVE-2015-4026)

  - PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not ensure that pathnames lack %00
    sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an
    application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function, as
    demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may
    write to only .html files. (CVE-2015-4598)

  - 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. (CVE-2015-4643)

  - The php_pgsql_meta_data function in pgsql.c in the PostgreSQL (aka pgsql) extension in PHP before 5.4.42,
    5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not validate token extraction for table names, which
    might allow remote attackers to cause a denial of service (NULL pointer dereference and application crash)
    via a crafted name. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1352.
    (CVE-2015-4644)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
