The remote host is affected by the vulnerability described in GLSA-201503-04 (GNU C Library: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in the GNU C Library.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A local attacker may be able to execute arbitrary code or cause a Denial       of Service condition,.
  Workaround :

    There is no known workaround at this time.

According to its model number and software version, the remote Xerox ColorQube device is affected by multiple OpenSSL vulnerabilities :

  - A man-in-the-middle (MitM) information disclosure     vulnerability, known as POODLE, exists due to the way     SSL 3.0 handles padding bytes when decrypting messages     encrypted using block ciphers in cipher block chaining     (CBC) mode. A MitM attacker can decrypt a selected byte     of a cipher text in as few as 256 tries if they are able     to force a victim application to repeatedly send the     same data over newly created SSL 3.0 connections.
    (CVE-2014-3566)

  - A security feature bypass vulnerability, known as FREAK     (Factoring attack on RSA-EXPORT Keys), exists due to the     support of weak EXPORT_RSA cipher suites with keys less     than or equal to 512 bits. A man-in-the-middle attacker     may be able to downgrade the SSL/TLS connection to use     EXPORT_RSA cipher suites which can be factored in a     short amount of time, allowing the attacker to intercept     and decrypt the traffic. (CVE-2015-0204)

  - A heap-based buffer overflow condition exists in the GNU     C Library (glibc) due to improper validation of     user-supplied input to 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. This     vulnerability is known as GHOST. (CVE-2015-0235)

Robert Kratky reports :

GHOST is a 'buffer overflow' bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library. This vulnerability allows a remote attacker that is able to make an application call to either of these functions to execute arbitrary code with the permissions of the user running the application. The gethostbyname() function calls are used for DNS resolving, which is a very common event. To exploit this vulnerability, an attacker must trigger a buffer overflow by supplying an invalid hostname argument to an application that performs a DNS resolution.

New glibc packages are available for Slackware 13.0, 13.1, 13.37, 14.0, and 14.1 to fix a security issue.

Several vulnerabilities have been fixed in eglibc, Debian's version of the GNU C library :

  - CVE-2015-0235     Qualys discovered that the gethostbyname and     gethostbyname2 functions were subject to a buffer     overflow if provided with a crafted IP address argument.
    This could be used by an attacker to execute arbitrary     code in processes which called the affected functions.

  The original glibc bug was reported by Peter Klotz.

  - CVE-2014-7817     Tim Waugh of Red Hat discovered that the WRDE_NOCMD     option of the wordexp function did not suppress command     execution in all cases. This allows a context-dependent     attacker to execute shell commands.

  - CVE-2012-6656 CVE-2014-6040     The charset conversion code for certain IBM multi-byte     code pages could perform an out-of-bounds array access,     causing the process to crash. In some scenarios, this     allows a remote attacker to cause a persistent denial of     service.

Updated glibc packages that fix one security issue are now available for Red Hat Enterprise Linux 5.

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.

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.

A vulnerability has been fixed in eglibc, Debian's version of the GNU C library :

CVE-2015-0235

Qualys discovered that the gethostbyname and gethostbyname2 functions were subject to a buffer overflow if provided with a crafted IP address argument. This could be used by an attacker to execute arbitrary code in processes which called the affected functions.

The original glibc bug was reported by Peter Klotz.

We recommend that you upgrade your eglibc packages.

The other three CVEs fixed in Debian wheezy via DSA 3142-1 have already been fixed in squeeze LTS via DLA DLA 97-1.

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