NASL id APPLETV_9_2.NASL description According to its banner, the remote Apple TV device is a version prior to 9.2. It is, therefore, affected by the following vulnerabilities : - An XML external entity (XXE) expansion flaw exists in libxml2 due to the XML parser accepting entities from untrusted sources. An unauthenticated, remote attacker can exploit this, via crafted XML data, to cause a denial of service through resource exhaustion. (CVE-2015-1819) - An XML external entity (XXE) injection flaw exists in libxml2 in file parser.c due to the XML parser accepting entities from untrusted sources. An unauthenticated, remote attacker can exploit this, via crafted XML data, to cause a denial of service or to disclose sensitive information. (CVE-2015-5312) - A heap buffer overflow condition exists in libxml2 in the xmlGROW() function within file parser.c while handling XML data. An unauthenticated, remote attacker can exploit this to disclose sensitive information.

An unauthenticated, remote attacker can exploit this to cause a denial of service. (CVE-2015-7500) - An out-of-bounds read error exists in libxml2 in the xmlParseConditionalSections() function within file parser.c due to a failure to properly skip intermediary entities when it stops parsing invalid input. An unauthenticated, remote attacker can exploit this, via crafted XML data, to cause a denial of service. (CVE-2015-7942) - A flaw exists in libxml2 in the xz_decomp() function within file xzlib.c due to a failure to properly detect compression errors when handling compressed XML content. An unauthenticated, remote attacker can exploit this, via crafted XML data, to cause an infinite loop, resulting in a denial of service. (CVE-2015-8035) - A out-of-bounds read error exists in libxml2 in the xmlSAX2TextNode() function within file SAX2.c due to improper sanitization of input data.

(CVE-2016-1750) - A flaw exists in the kernel due to a failure to properly restrict execution permissions. An unauthenticated, remote attacker can exploit this, via a crafted application, to bypass code-signing protection mechanisms. (CVE-2016-1751) - An unspecified flaw exists in the kernel that allows a local attacker to cause a denial of service via a crafted application. (CVE-2016-1752) - An integer overflow condition exists in the kernel due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a crafted application, to gain elevated privileges. (CVE-2016-1753) - A memory corruption issue exists in the kernel due to improper validation of user-supplied input.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The libxml2 library is a development toolbox providing the implementation of various XML standards. Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application.

An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory. The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941 . libxml2 2.9.2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function in parser.c, as demonstrated by non-terminated entities. A heap-based buffer overflow vulnerability was found in xmlDictComputeFastQKey in dict.c. A heap-based buffer overflow read in xmlParseMisc was found. A heap-based buffer overflow was found in xmlGROW allowing the attacker to read the memory out of bounds. A buffer overread in xmlNextChar was found, causing segmentation fault when compiled with ASAN. Heap-based buffer overflow was found in xmlParseXmlDecl. When conversion failure happens, parser continues to extract more errors which may lead to unexpected behaviour. Stack-based buffer overread vulnerability with HTML parser in push mode in xmlSAX2TextNode causing segmentation fault when compiled with ASAN. A vulnerability in libxml2 was found causing DoS by exhausting CPU when parsing specially crafted XML document. An out-of-bounds heap read in xmlParseXMLDecl happens when a file containing unfinished xml declaration. last seen 2020-06-01 modified 2020-06-02 plugin id 87354 published 2015-12-15 reporter This script is Copyright (C) 2015-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/87354 title Amazon Linux AMI : libxml2 (ALAS-2015-628) NASL family MacOS X Local Security Checks NASL id MACOSX_SECUPD2016-002.NASL description The remote host is running a version of Mac OS X that is 10.9.5 or 10.10.5 and is missing Security Update 2016-002.
