18 Feb 2025 — 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. • https://gitlab.gnome.org/GNOME/libxml2/-/issues/828 • CWE-416: Use After Free •

18 Feb 2025 — 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. • https://gitlab.gnome.org/GNOME/libxml2/-/issues/847 • CWE-121: Stack-based Buffer Overflow •

26 Jan 2025 — xmlXIncludeAddNode in xinclude.c in libxml2 before 2.11.0 has a use-after-free. A flaw was found in libxml2 where improper handling of memory allocation failures in `libxml2` can lead to crashes, memory leaks, or inconsistent states. While an attacker cannot directly control allocation failures, they may trigger denial-of-service conditions under extreme system stress. It was discovered that libxml2 incorrectly handled certain memory operations. A remote attacker could use this issue to cause libxml2 to cra... • https://github.com/php/php-src/issues/17467 • CWE-416: Use After Free •

23 Dec 2024 — 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. En libxml2 2.11 anterior a 2.11.9, 2.12 anterior a 2.12.9 y 2.13 anterior a 2.13.3, el analizador SAX puede producir eventos para entidades externas incluso si los controladores SAX personalizados intentan anular el contenido de la entidad (estableciendo "m... • https://gitlab.gnome.org/GNOME/libxml2/-/commit/1a8932303969907f6572b1b6aac4081c56adb5c6 • CWE-611: Improper Restriction of XML External Entity Reference •

04 Feb 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. Se descubrió un problema en libxml2 anterior a 2.11.7 y 2.12.x anterior a 2.12.5.

06 Oct 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." ** EN DISPUTA ** libxml2 hasta 2.11.5 tiene un use-after-free que solo puede ocurrir después de que falla una determinada asignación de memoria. Esto ocurre en xmlUnlinkNode en tree.c. NOTA... • http://www.openwall.com/lists/oss-security/2023/10/06/5 • CWE-416: Use After Free •

29 Aug 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. A flaw was found in Libxml2, where it contains a global buffer overflow via the xmlSAX2StartElement() function at /li... • https://gitlab.gnome.org/GNOME/libxml2/-/issues/535 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
