readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (file descriptor consumption) via a large number of crafted XML files.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - expat: resource leak in readfilemap.c (CVE-2012-1147)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

The version of Apple iTunes installed on the remote macOS or Mac OS X host is prior to 12.6. It is, therefore, affected by multiple vulnerabilities :

  - Multiple vulnerabilities exist in the expat component,     the most severe of which are remote code execution     vulnerabilities. An unauthenticated, remote attacker can     exploit these vulnerabilities to cause a denial of     service condition or the execution of arbitrary code in     the context of the current user. (CVE-2009-3270,     CVE-2009-3560, CVE-2009-3720, CVE-2012-1147,     CVE-2012-1148, CVE-2012-6702, CVE-2015-1283,     CVE-2016-0718, CVE-2016-4472, CVE-2016-5300)

  - Multiple vulnerabilities exist in the SQLite component,     the most severe of which are remote code execution     vulnerabilities. An unauthenticated, remote attacker can     exploit these vulnerabilities by convincing a user to     open a specially crafted file, to cause a denial of     service condition or the execution of arbitrary code in     the context of the current user. (CVE-2013-7443,     CVE-2015-3414, CVE-2015-3415, CVE-2015-3416,     CVE-2015-3717, CVE-2015-6607, CVE-2016-6153)

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

  - An information disclosure vulnerability exists in the     APNs server component due to client certificates being     transmitted in cleartext. A man-in-the-middle attacker     can exploit this to disclose sensitive information.
    (CVE-2017-2383)

  - A use-after-free error exists in the WebKit component     due to improper handling of RenderBox objects. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-2463)

  - Multiple universal cross-site scripting (XSS)     vulnerabilities exist in the WebKit component due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit these     vulnerabilities, by convincing a user to visit a     specially crafted web page, to execute arbitrary script     code in a user's browser session. (CVE-2017-2479,     CVE-2017-2480, CVE-2017-2493)

  - An integer overflow condition exists in the libxslt     component in the xsltAddTextString() function in     transform.c due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     this to cause an out-of-bounds write, resulting in the     execution of arbitrary code. (CVE-2017-5029)
