RockyLinux 9 : libxml2 (RLSA-2026:71585)

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:71585 advisory. libxml2: libxml2: Arbitrary code execution via heap-based buffer overflow CVE-2026-86138 libxml2: libxml2: Data integrity issues due to integer overflow...

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: 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: 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: 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...

Important: Red Hat Security Advisory: libxml2 security update

An update for libxml2 is now available for Red Hat Enterprise Linux 9. 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 for each vulnerability from t...

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...
