CVE-2025-32415 1 Xmlsoft 1 Libxml2 2025-11-03 2.9 Low
In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used.
CVE-2025-32414 2 Redhat, Xmlsoft 2 Enterprise Linux, Libxml2 2025-11-03 5.6 Medium
In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters.
CVE-2023-28484 3 Debian, Redhat, Xmlsoft 5 Debian Linux, Enterprise Linux, Jboss Core Services and 2 more 2025-05-30 6.5 Medium
In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault. This occurs in xmlSchemaFixupComplexType in xmlschemas.c.
CVE-2022-23308 7 Apple, Debian, Fedoraproject and 4 more 46 Ipados, Iphone Os, Mac Os X and 43 more 2025-05-05 7.5 High
valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes.
CVE-2022-40303 4 Apple, Netapp, Redhat and 1 more 25 Ipados, Iphone Os, Macos and 22 more 2025-04-29 7.5 High
An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault.
CVE-2022-40304 4 Apple, Netapp, Redhat and 1 more 25 Ipados, Iphone Os, Macos and 22 more 2025-04-28 7.8 High
An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked.
CVE-2016-4483 4 Debian, Oracle, Redhat and 1 more 4 Debian Linux, Solaris, Jboss Core Services and 1 more 2025-04-20 7.5 High
The xmlBufAttrSerializeTxtContent function in xmlsave.c in libxml2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a non-UTF-8 attribute value, related to serialization. NOTE: this vulnerability may be a duplicate of CVE-2016-3627.
CVE-2017-16931 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
parser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name.
CVE-2017-5969 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser.
CVE-2017-9047 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
CVE-2015-8710 3 Debian, Redhat, Xmlsoft 4 Debian Linux, Enterprise Linux, Jboss Enterprise Web Server and 1 more 2025-04-12 9.8 Critical
The htmlParseComment function in HTMLparser.c in libxml2 allows attackers to obtain sensitive information, cause a denial of service (out-of-bounds heap memory access and application crash), or possibly have unspecified other impact via an unclosed HTML comment.
CVE-2015-6837 3 Php, Redhat, Xmlsoft 3 Php, Rhel Software Collections, Libxml2 2025-04-12 N/A
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-2015-7942 6 Apple, Canonical, Debian and 3 more 11 Iphone Os, Mac Os X, Tvos and 8 more 2025-04-12 N/A
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.
CVE-2016-4658 3 Apple, Redhat, Xmlsoft 6 Iphone Os, Mac Os X, Tvos and 3 more 2025-04-12 N/A
xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document.
CVE-2014-3660 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2025-04-12 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-2015-5312 6 Apple, Canonical, Debian and 3 more 15 Iphone Os, Mac Os X, Tvos and 12 more 2025-04-12 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-2015-6838 3 Php, Redhat, Xmlsoft 3 Php, Rhel Software Collections, Libxml2 2025-04-12 N/A
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-2015-7498 5 Canonical, Debian, Hp and 2 more 11 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 8 more 2025-04-12 N/A
