    It was discovered that libxml2 incorrectly handled certain memory operations. A remote attacker could use     this issue to cause libxml2 to crash, resulting in a denial of service, or possibly execute arbitrary     code.

    It was discovered that the libxml2 xmllint tool incorrectly handled certain memory operations. If a user     or automated system were tricked into running xmllint on a specially crafted xml file, a remote attacker     could cause xmllint to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS,     Ubuntu 16.04 LTS, and Ubuntu 18.04 LTS. (CVE-2024-34459)

    Package        : libxml2     Version        : 2.9.10+dfsg-6.7+deb11u6     CVE ID         : CVE-2022-49043 CVE-2023-39615 CVE-2023-45322 CVE-2024-25062                      CVE-2024-56171 CVE-2025-24928 CVE-2025-27113     Debian Bug     : 1051230 1053629 1063234 1094238 1098320 1098321 1098322

    Multiple vulnerabilities have been found in libxml2, a library providing     support to read, modify and write XML and HTML files. These     vulnerabilities could potentially lead to denial of servie or other     unintended behaviors.

    CVE-2022-49043

        xmlXIncludeAddNode in xinclude.c in libxml2 before 2.11.0 has a         use-after-free.

    CVE-2023-39615

        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-2023-45322

        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-2024-25062

        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-2024-56171

        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-2025-24928

        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-2025-27113

        libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a NULL pointer         dereference in xmlPatMatch in pattern.c.

    For Debian 11 bullseye, these problems have been fixed in version     2.9.10+dfsg-6.7+deb11u6.

    We recommend that you upgrade your libxml2 packages.
