libxml2: libxml2: Arbitrary code execution via heap-based buffer overflow

A flaw was found in libxml2, a software library for parsing XML documents. An integer overflow within the xmlDictAddQString function can lead to a heap-based buffer overflow. This vulnerability could allow a local attacker to execute arbitrary code on the system, potentially compromising its...

libxml2: double-free/UAF in libxml2 Python bindings

A flaw was found in libxml2 with Python bindings enabled. A remote attacker could exploit this vulnerability by providing a specially crafted XML document containing a Document Type Definition DTD with enumerated attribute values. This triggers a double-free error in the SAX attributeDecl callbac...

libxml2: libxml2: Arbitrary code execution via stack-based buffer overflow in xmlSnprintfElements

A flaw was found in libxml2. A local attacker could exploit a stack-based buffer overflow in the xmlSnprintfElements function to achieve arbitrary code execution. This vulnerability in a fundamental system library could lead to significant system compromise if successfully exploited...

libxml2: libxml2: Heap-based buffer overflow in xmlXPtrEval due to xpointer length saturation

A flaw in libxml2's xmlXPtrEvalXPtrPart function allows a local attacker to cause a heap-based buffer overflow. An integer overflow while processing an oversized xpointer expression leads to incorrect memory allocation and an out-of-bounds write, potentially resulting in information disclosure,...
