CVE-2015-7941 2 Canonical, Xmlsoft 2 Ubuntu Linux, Libxml2 2023-12-10 4.3 MEDIUM N/A
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.
CVE-2015-8242 5 Apple, Canonical, Hp and 2 more 12 Iphone Os, Mac Os X, Tvos and 9 more 2023-12-10 5.8 MEDIUM N/A
The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.
CVE-2016-2073 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxml2 2023-12-10 4.3 MEDIUM 6.5 MEDIUM
The htmlParseNameComplex function in HTMLparser.c in libxml2 allows attackers to cause a denial of service (out-of-bounds read) via a crafted XML document.
CVE-2016-4449 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxml2 2023-12-10 5.8 MEDIUM 7.1 HIGH
XML external entity (XXE) vulnerability in the xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.4, when not in validating mode, allows context-dependent attackers to read arbitrary files or cause a denial of service (resource consumption) via unspecified vectors.

Use-after-free vulnerability in the xmlDictComputeFastKey function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service via a crafted XML document.
CVE-2015-6838 2 Php, Xmlsoft 2 Php, Libxml2 2023-12-10 5.0 MEDIUM 7.5 HIGH
The xsl_ext_function_php function in ext/xsl/xsltprocessor.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13, when libxml2 before 2.9.2 is used, does not consider the possibility of a NULL valuePop return value before proceeding with a free operation after the principal argument loop, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted XML document, a different vulnerability than CVE-2015-6837.

The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.
CVE-2016-1838 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
The xmlPArserPrintFileContextInternal function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
CVE-2016-1840 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2023-12-10 6.8 MEDIUM 7.8 HIGH
Heap-based buffer overflow in the xmlFAParsePosCharGroup function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.
CVE-2016-4447 8 Apple, Canonical, Debian and 5 more 12 Iphone Os, Itunes, Mac Os X and 9 more 2023-12-10 5.0 MEDIUM 7.5 HIGH
The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName.
CVE-2016-1839 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
The xmlDictAddString function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
CVE-2013-0339 4 Canonical, Debian, Suse and 1 more 4 Ubuntu Linux, Debian Linux, Linux Enterprise Server and 1 more 2023-12-10 6.8 MEDIUM N/A
libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because libxml2 already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed and each affected application would need its own CVE.
CVE-2014-3660 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2023-12-10 5.0 MEDIUM N/A
parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.
CVE-2013-0338 3 Canonical, Opensuse, Xmlsoft 3 Ubuntu Linux, Opensuse, Libxml2 2023-12-10 4.3 MEDIUM N/A
libxml2 2.9.0 and earlier allows context-dependent attackers to cause a denial of service (CPU and memory consumption) via an XML file containing an entity declaration with long replacement text and many references to this entity, aka "internal entity expansion" with linear complexity.
CVE-2012-2871 3 Apple, Google, Xmlsoft 3 Iphone Os, Chrome, Libxml2 2023-12-10 6.8 MEDIUM N/A
libxml2 2.9.0-rc1 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly support a cast of an unspecified variable during handling of XSL transforms, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted document, related to the _xmlNs data structure in include/libxml/tree.h.
CVE-2012-5134 3 Apple, Google, Xmlsoft 3 Iphone Os, Chrome, Libxml2 2023-12-10 6.8 MEDIUM N/A
Heap-based buffer underflow in the xmlParseAttValueComplex function in parser.c in libxml2 2.9.0 and earlier, as used in Google Chrome before 23.0.1271.91 and other products, allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted entities in an XML document.
CVE-2013-1969 1 Xmlsoft 1 Libxml2 2023-12-10 7.5 HIGH N/A
Multiple use-after-free vulnerabilities in libxml2 2.9.0 and possibly other versions might allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to the (1) htmlParseChunk and (2) xmldecl_done functions, as demonstrated by a buffer overflow in the xmlBufGetInputBase function.
