| CVE-2025-27113 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 2.9 LOW |
| libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a NULL pointer dereference in xmlPatMatch in pattern.c. | |||||
| CVE-2025-24928 | 2 Netapp, Xmlsoft | 16 Active Iq Unified Manager, H300s, H300s Firmware and 13 more | 2026-06-17 | N/A | 7.8 HIGH |
| libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a stack-based buffer overflow in xmlSnprintfElements in valid.c. To exploit this, DTD validation must occur for an untrusted document or untrusted DTD. NOTE: this is similar to CVE-2017-9047. | |||||
| CVE-2024-56171 | 2 Netapp, Xmlsoft | 16 Active Iq Unified Manager, H300s, H300s Firmware and 13 more | 2026-06-17 | N/A | 7.8 HIGH |
| libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a use-after-free in xmlSchemaIDCFillNodeTables and xmlSchemaBubbleIDCNodeTables in xmlschemas.c. 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-2024-40896 | 2 Netapp, Xmlsoft | 14 H300s, H300s Firmware, H410c and 11 more | 2026-06-17 | N/A | 9.1 CRITICAL |
| In libxml2 2.11 before 2.11.9, 2.12 before 2.12.9, and 2.13 before 2.13.3, the SAX parser can produce events for external entities even if custom SAX handlers try to override entity content (by setting "checked"). This makes classic XXE attacks possible. | |||||
| CVE-2024-34459 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 7.5 HIGH |
| An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c. | |||||
| CVE-2024-25062 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 7.5 HIGH |
| An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free. | |||||
| CVE-2023-45322 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 6.5 MEDIUM |
| libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail." | |||||
| CVE-2023-39615 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 6.5 MEDIUM |
| Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input. | |||||
| CVE-2023-29469 | 2 Debian, Xmlsoft | 2 Debian Linux, Libxml2 | 2026-06-17 | N/A | 6.5 MEDIUM |
| An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value). | |||||
| CVE-2023-28484 | 2 Debian, Xmlsoft | 2 Debian Linux, Libxml2 | 2026-06-17 | N/A | 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-2022-49043 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | N/A | 8.1 HIGH |
| xmlXIncludeAddNode in xinclude.c in libxml2 before 2.11.0 has a use-after-free. | |||||
| CVE-2022-40304 | 3 Apple, Netapp, Xmlsoft | 22 Ipados, Iphone Os, Macos and 19 more | 2026-06-17 | N/A | 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-2022-40303 | 3 Apple, Netapp, Xmlsoft | 22 Ipados, Iphone Os, Macos and 19 more | 2026-06-17 | N/A | 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-2022-2309 | 3 Fedoraproject, Lxml, Xmlsoft | 3 Fedora, Lxml, Libxml2 | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered. | |||||
| CVE-2022-29824 | 5 Debian, Fedoraproject, Netapp and 2 more | 24 Debian Linux, Fedora, Active Iq Unified Manager and 21 more | 2026-06-17 | 4.3 MEDIUM | 6.5 MEDIUM |
| In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. | |||||
| CVE-2022-23308 | 6 Apple, Debian, Fedoraproject and 3 more | 44 Ipados, Iphone Os, Mac Os X and 41 more | 2026-06-17 | 4.3 MEDIUM | 7.5 HIGH |
| valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes. | |||||
| CVE-2021-3541 | 4 Netapp, Oracle, Redhat and 1 more | 27 Active Iq Unified Manager, Cloud Backup, Clustered Data Ontap and 24 more | 2026-06-17 | 4.0 MEDIUM | 6.5 MEDIUM |
| A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service. | |||||
| CVE-2021-3537 | 6 Debian, Fedoraproject, Netapp and 3 more | 20 Debian Linux, Fedora, Active Iq Unified Manager and 17 more | 2026-06-17 | 4.3 MEDIUM | 5.9 MEDIUM |
| A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3518 | 6 Debian, Fedoraproject, Netapp and 3 more | 19 Debian Linux, Fedora, Active Iq Unified Manager and 16 more | 2026-06-17 | 6.8 MEDIUM | 8.8 HIGH |
| There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability. | |||||
| CVE-2021-3517 | 6 Debian, Fedoraproject, Netapp and 3 more | 29 Debian Linux, Fedora, Active Iq Unified Manager and 26 more | 2026-06-17 | 7.5 HIGH | 8.6 HIGH |
| There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application. | |||||
