| 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-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-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-2017-5969 | 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-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-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. | ||||

| The xmlNextChar function in libxml2 2.9.2 does not properly check the state, which allows context-dependent attackers to cause a denial of service (heap-based buffer over-read and application crash) or obtain sensitive information via crafted XML data. | ||||
| 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. | ||||
