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 /libxml2/SAX2.c. This vulnerability allows attackers to cause a denial of service (DoS) by supplying a crafted XML file.
Brief introduction Multiple memory related vulnerabilities, including use-after-free, out-of-bounds memory access and NULL pointer dereference, were discovered in GNOME XML Parser and Toolkit Library and its Python bindings, which may cause denial of service or other unintended behaviors. For the stable distribution (bookworm), these problems have been fixed in version 2.9.14+dfsg-1.3~deb12u2.
