The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2015-0090 advisory.

    [2.5-123.0.1.el5_11.1]
    - Switch to use malloc when the input line is too long [Orabug 19951108]
    - Use a /sys/devices/system/cpu/online for _SC_NPROCESSORS_ONLN implementation [Orabug 17642251] (Joe Jin)

    [2.5-123.1]
    - Fix parsing of numeric hosts in gethostbyname_r (CVE-2015-0235, #1183532).

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated glibc packages that fix one security issue are now available for Red Hat Enterprise Linux 5.6 Long Life, Red Hat Enterprise Linux 5.9 Extended Update Support, Red Hat Enterprise Linux 6.2 Advanced Update Support, and Red Hat Enterprise Linux 6.4 and 6.5 Extended Update Support.

Red Hat Product Security has rated this update as having Critical security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the Name Server Caching Daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly.

A heap-based buffer overflow was found in glibc's
__nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. (CVE-2015-0235)

Red Hat would like to thank Qualys for reporting this issue.

All glibc users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

(CVE-2015-0273)

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2015:0126 advisory.

    The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization     Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor     is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes     everything necessary to run and manage virtual machines: a subset of the     Red Hat Enterprise Linux operating environment and the Red Hat Enterprise     Virtualization Agent.

    Note: Red Hat Enterprise Virtualization Hypervisor is only available for     the Intel 64 and AMD64 architectures with virtualization extensions.

    A heap-based buffer overflow was found in glibc's
    __nss_hostname_digits_dots() function, which is used by the gethostbyname()     and gethostbyname2() glibc function calls. A remote attacker able to make     an application call either of these functions could use this flaw to     execute arbitrary code with the permissions of the user running the     application. (CVE-2015-0235)

    A race condition flaw was found in the way the Linux kernel's KVM subsystem     handled PIT (Programmable Interval Timer) emulation. A guest user who has     access to the PIT I/O ports could use this flaw to crash the host.
    (CVE-2014-3611)

    A flaw was found in the way OpenSSL handled fragmented handshake packets.
    A man-in-the-middle attacker could use this flaw to force a TLS/SSL server     using OpenSSL to use TLS 1.0, even if both the client and the server     supported newer protocol versions. (CVE-2014-3511)

    A memory leak flaw was found in the way an OpenSSL handled failed session     ticket integrity checks. A remote attacker could exhaust all available     memory of an SSL/TLS or DTLS server by sending a large number of invalid     session tickets to that server. (CVE-2014-3567)

    It was found that the Linux kernel's KVM subsystem did not handle the VM     exits gracefully for the invept (Invalidate Translations Derived from EPT)     and invvpid (Invalidate Translations Based on VPID) instructions. On hosts     with an Intel processor and invept/invppid VM exit support, an unprivileged     guest user could use these instructions to crash the guest. (CVE-2014-3645,     CVE-2014-3646)

    Red Hat would like to thank Qualys for reporting the CVE-2015-0235 issue,     Lars Bull of Google for reporting the CVE-2014-3611 issue, and the Advanced     Threat Research team at Intel Security for reporting the CVE-2014-3645 and     CVE-2014-3646 issues.

    Users of the Red Hat Enterprise Virtualization Hypervisor are advised to     upgrade to this updated package.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

It was discovered that a buffer overflow existed in the gethostbyname and gethostbyname2 functions in the GNU C Library. An attacker could use this issue to execute arbitrary code or cause an application crash, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Versions of PHP 5.4.x earlier than 5.4.38, 5.5.x earlier than 5.5.22, or 5.6.x earlier than 5.6.6 are exposed to the following issues :

  - A heap-based buffer overflow flaw in the GNU C Library (glibc) due to improperly validating user-supplied input in the glibc functions __nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (GHOST) (Bug 68925 / CVE-2015-0235)

  - A use-after-free flaw exists in the function php_date_timezone_initialize_from_hash() within the 'ext/date/php_date.c' script. An attacker can exploit this to access sensitive information or crash applications linked to PHP. (Bug 68942 / CVE-2015-0273)

  - A use-after-free flaw exists in the function 'phar_rename_archive' in the source file 'phar_object.c'. An attacker can cause a denial of service or possibly have unspecified other impact via vectors that trigger an attempted renaming of a Phar archive to the name of an existing file. (Bug 68901 / CVE-2015-2301)

  - A heap-based buffer overflow flaw affects the 'enchant_broker_request_dict' function in the source file 'ext/enchant/enchant.c'. This allows remote attackers to execute arbitrary code via vectors that trigger creation of multiple dictionaries. (Bug 68552 / CVE-2014-9705)
