Recent Xmlsoft Security Vulnerabilities
An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5
CVE-2024-25062
7.5 - High
- February 04, 2024
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.
Dangling pointer
libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails
CVE-2023-45322
6.5 - Medium
- October 06, 2023
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."
Dangling pointer
Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c
CVE-2023-39615
6.5 - Medium
- August 29, 2023
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.
Buffer Overflow
An issue was discovered in libxml2 before 2.10.4
CVE-2023-29469
6.5 - Medium
- April 24, 2023
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).
Double-free
In libxml2 before 2.10.4, parsing of certain invalid XSD schemas can lead to a NULL pointer dereference and subsequently a segfault
CVE-2023-28484
6.5 - Medium
- April 24, 2023
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.
NULL Pointer Dereference
An issue was discovered in libxml2 before 2.10.3
CVE-2022-40304
7.8 - High
- November 23, 2022
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.
Double-free
An issue was discovered in libxml2 before 2.10.3
CVE-2022-40303
7.5 - High
- November 23, 2022
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.
Integer Overflow or Wraparound
Possible cross-site scripting vulnerability in libxml after commit 960f0e2.
CVE-2016-3709
6.1 - Medium
- July 28, 2022
Possible cross-site scripting vulnerability in libxml after commit 960f0e2.
XSS
In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows
CVE-2022-29824
6.5 - Medium
- May 03, 2022
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.
Integer Overflow or Wraparound
valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes.
CVE-2022-23308
7.5 - High
- February 26, 2022
valid.c in libxml2 before 2.9.13 has a use-after-free of ID and IDREF attributes.

Use after free in Blink XSLT in Google Chrome prior to 91.0.4472.164
CVE-2021-30560
8.8 - High
- August 03, 2021
Use after free in Blink XSLT in Google Chrome prior to 91.0.4472.164 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

XEE
There's a flaw in libxml2's xmllint in versions before 2.9.11
CVE-2021-3516
7.8 - High
- June 01, 2021
There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability.
