Important: Red Hat Security Advisory: libxml2 security update
An update for libxml2 is now available for Red Hat Enterprise Linux 10.0 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available fo...
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,...
libxml2: libxml2: Information disclosure, SSRF, or denial of service due to improper parseFlags propagation.
A flaw in libxml2's XInclude processing xmlXIncludeProcess and xmlXIncludeProcessTree fails to propagate parser flags like XMLPARSENONET. This allows custom resource loaders to fetch external network resources, potentially enabling Server-Side Request Forgery SSRF, XML External Entity XXE...
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: 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: 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,...
Important: Red Hat Security Advisory: libxml2 security update
An update for libxml2 is now available for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is...
libxml2: libxml2: Arbitrary code execution in xmlcatalog utility via buffer overflow
A flaw was found in libxml2, specifically within the xmlcatalog utility when operating in shell mode. An attacker can exploit multiple stack-based buffer overflows by providing an excessively long input line. This leads to memory corruption, which may cause the application to crash or potentially...
libxml2: libxml2: Information disclosure, SSRF, or denial of service due to improper parseFlags propagation.

libxml2: mingw-libxml2: libxml2: Denial of Service via crafted XML input due to use-after-free
A flaw was found in libxml2. A remote attacker can exploit a use-after-free vulnerability in the xmlParseInternalSubset function by providing maliciously crafted XML input. This improper handling of entity resolution can lead to a denial-of-service DoS, making the affected system or application...
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: Data integrity issues due to integer overflow in write callbacks
An integer overflow in the libxml2 xmlIO module occurs when data backlogs exceed maximum integer limits. This flaw passes negative length values to downstream write callbacks, creating an unsafe state that can lead to data corruption or compromise application confidentiality and integrity...
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...
