A vulnerability has been found and corrected in libarchive :

Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on 64-bit systems where sizeof(size_t) is equal to 8. In the archive_write_zip_data() function in libarchive/ archive_write_set_format_zip.c, the 's' parameter is of type size_t (64 bit, unsigned) and is cast to a 64 bit signed integer. If 's' is larger than MAX_INT, it will not be set to 'zip->remaining_data_bytes' even though it is larger than 'zip->remaining_data_bytes', which leads to a buffer overflow when calling deflate(). This can lead to a segfault in an application that uses libarchive to create ZIP archives (CVE-2013-0211).

The updated packages have been patched to correct this issue.

It was discovered that the libarchive bsdcpio utility extracted absolute paths by default without using the --insecure flag, contrary to expectations. If a user or automated system were tricked into extracting cpio archives containing absolute paths, a remote attacker may be able to write to arbitrary files. (CVE-2015-2304)

Fabian Yamaguchi discovered that libarchive incorrectly handled certain type conversions. A remote attacker could possibly use this issue to cause libarchive to crash, resulting in a denial of service.
This issue only affected Ubuntu 12.04 LTS. (CVE-2013-0211).

  - A flaw was found in the way libarchive handled hardlink     archive entries of non-zero size. Combined with flaws     in libarchive's file system sandboxing, this issue     could cause an application using libarchive to     overwrite arbitrary files with arbitrary data from the     archive.(CVE-2016-5418)

  - Integer signedness error in the archive_write_zip_data     function in archive_write_set_format_zip.c in     libarchive 3.1.2 and earlier, when running on 64-bit     machines, allows context-dependent attackers to cause a     denial of service (crash) via unspecified vectors,     which triggers an improper conversion between unsigned     and signed types, leading to a buffer     overflow.(CVE-2013-0211)

  - A vulnerability was found in libarchive. A specially     crafted zip file can provide an incorrect compressed     size, which may allow an attacker to place arbitrary     code on the heap and execute it in the context of the     application.(CVE-2016-1541)

MITRE reports :

Integer signedness error in the archive_write_zip_data function in archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running on 64-bit machines, allows context-dependent attackers to cause a denial of service (crash) via unspecified vectors, which triggers an improper conversion between unsigned and signed types, leading to a buffer overflow.

Absolute path traversal vulnerability in bsdcpio in libarchive 3.1.2 and earlier allows remote attackers to write to arbitrary files via a full pathname in an archive.

Libarchive issue tracker reports :

Using a crafted tar file bsdtar can perform an out-of-bounds memory read which will lead to a SEGFAULT. The issue exists when the executable skips data in the archive. The amount of data to skip is defined in byte offset [16-19] If ASLR is disabled, the issue can lead to an infinite loop.

The remote host is affected by the vulnerability described in GLSA-201406-02 (libarchive: Multiple vulnerabilities)

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

    A remote attacker could entice a user or automated process to open a       specially crafted archive using an application linked against libarchive,       possibly resulting in execution of arbitrary code with the privileges of       the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

libarchive was updated to fix a directory traversal in the bsdcpio tool, which allowed attackers supplying crafted archives to overwrite files. (CVE-2015-2304)

Also, a integer overflow was fixed that could also overflow buffers.
(CVE-2013-0211)

According to its self-reported version number, the version of Splunk Enterprise hosted on the remote web server is 5.0.x, 6.0.x prior to 6.0.12, 6.1.x prior to 6.1.11, 6.2.x prior to 6.2.11, 6.3.x prior to 6.3.6, or 6.4.x prior to 6.4.2; or else it is Splunk Light version 6.4.x prior to 6.4.2. It is, therefore, affected by the following vulnerabilities :

  - An integer signedness error exists in libarchive in the     archive_write_zip_data() function within file     archive_write_set_format_zip.c due to improper     conversion between unsigned and signed integer types     when running on 64-bit CPUs. An unauthenticated, remote     attacker can exploit this to cause a buffer overflow,     resulting in a denial of service condition.
    (CVE-2013-0211)

  - A path traversal vulnerability exists in libarchive in     the bsdcpio() function within file in cpio/cpio.c due to     improper sanitization of user-supplied input. An     unauthenticated, remote attacker can exploit this, via     a specially crafted path in an archive, to write to     arbitrary files. (CVE-2015-2304)

  - A heap-based buffer overflow condition exists in     libarchive in the zip_read_mac_metadata() function     within file archive_read_support_format_zip.c due to     improper sanitization of user-supplied input. An     unauthenticated, remote attacker can exploit this, via     specially crafted entry-size values in a ZIP archive, to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-1541)

  - Multiple flaws exist in the OpenSSL library in the     aesni_cbc_hmac_sha1_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha1.c and the     aesni_cbc_hmac_sha256_cipher() function in file     crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered     when the connection uses an AES-CBC cipher and AES-NI     is supported by the server. A man-in-the-middle attacker     can exploit these to conduct a padding oracle attack,     resulting in the ability to decrypt the network traffic.
    (CVE-2016-2107)

  - An unspecified cross-site scripting (XSS) vulnerability     exists due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     this, via a specially crafted request, to execute     arbitrary script code in the user's browser session.

  - An unspecified cross-site redirection vulnerability     exists due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     this, by convincing a user to visit a specially crafted     web link, to redirect the browser to an arbitrary     website of the attacker's own choosing.

Note that Splunk Enterprise 5.0.x will not be patched for OpenSSL issues, and it is recommended you upgrade to the latest version.

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