CVE-2015-7497 5 Canonical, Debian, Hp and 2 more 9 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 6 more 2024-11-21 5.0 MEDIUM N/A
Heap-based buffer overflow in the xmlDictComputeFastQKey function in dict.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors.
CVE-2015-6838 2 Php, Xmlsoft 2 Php, Libxml2 2024-11-21 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.
CVE-2015-6837 2 Php, Xmlsoft 2 Php, Libxml2 2024-11-21 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 during initial error checking, 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-2015-6838.
CVE-2015-5312 6 Apple, Canonical, Debian and 3 more 13 Iphone Os, Mac Os X, Tvos and 10 more 2024-11-21 7.1 HIGH N/A
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-2014-3660 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2024-11-21 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-2013-2877 2 Google, Xmlsoft 2 Chrome, Libxml2 2024-11-21 5.0 MEDIUM N/A
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state.
CVE-2013-1969 1 Xmlsoft 1 Libxml2 2024-11-21 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.
CVE-2013-0339 4 Canonical, Debian, Suse and 1 more 4 Ubuntu Linux, Debian Linux, Linux Enterprise Server and 1 more 2024-11-21 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-2013-0338 3 Canonical, Opensuse, Xmlsoft 3 Ubuntu Linux, Opensuse, Libxml2 2024-11-21 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-2012-5134 3 Apple, Google, Xmlsoft 3 Iphone Os, Chrome, Libxml2 2024-11-21 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-2012-2871 3 Apple, Google, Xmlsoft 3 Iphone Os, Chrome, Libxml2 2024-11-21 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-2012-0841 2 Apple, Xmlsoft 2 Iphone Os, Libxml2 2024-11-21 5.0 MEDIUM N/A
libxml2 before 2.8.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data.
CVE-2011-1944 1 Xmlsoft 2 Libxml, Libxml2 2024-11-21 9.3 HIGH N/A
Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.
CVE-2010-4494 10 Apache, Apple, Debian and 7 more 17 Openoffice, Iphone Os, Itunes and 14 more 2024-11-21 7.5 HIGH N/A

libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.
CVE-2009-2416 11 Apple, Canonical, Debian and 8 more 19 Iphone Os, Mac Os X, Mac Os X Server and 16 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework.

Stack consumption vulnerability in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allows context-dependent attackers to cause a denial of service (application crash) via a large depth of element declarations in a DTD, related to a function recursion, as demonstrated by the Codenomicon XML fuzzing framework.
CVE-2008-4409 1 Xmlsoft 1 Libxml2 2024-11-21 5.0 MEDIUM N/A
libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.
CVE-2008-3529 4 Apple, Canonical, Debian and 1 more 6 Iphone Os, Mac Os X, Safari and 3 more 2024-11-21 10.0 HIGH N/A
