libxml2: libxml2: Denial of Service via uncontrolled recursion in XML catalog processing

A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a...

Important: Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

An update for Red Hat Hardened Images RPMs is now available. This update includes the following RPMs: libxml2: libxml2-16-2.15.2-0.3.hum1 aarch64, x8664 libxml2-2.15.2-0.3.hum1 aarch64, x8664 libxml2-devel-2.15.2-0.3.hum1 aarch64, x8664 libxml2-static-2.15.2-0.3.hum1 aarch64, x8664...

libxml2: Libxml2 out of bounds read

An out of bounds read flaw has been discovered in libxml2. This flaw could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation...

libxml2: Unbounded RelaxNG Include Recursion Leading to Stack Overflow

A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may...

libxml: Type confusion leads to Denial of service (DoS)

A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined...

libxslt: libxml2: Inifinite recursion at exsltDynMapFunction function in libexslt/dynamic.c

A flaw was found in libxstl/libxml2. The 'exsltDynMapFunction' function in libexslt/dynamic.c does not contain a recursion depth check, which may cause an infinite loop via a specially crafted XSLT document while handling 'dyn:map', leading to stack exhaustion and a local denial of service...

libxml2: libxml2: Denial of Service via crafted XML catalogs

A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted catalogs, causing the parser to...

libxml2: Out-of-Bounds Read in libxml2

A flaw was found in libxml2. This vulnerability allows out-of-bounds memory access due to incorrect handling of return values in xmlPythonFileRead and xmlPythonFileReadRaw. This is caused by a mismatch between the length of the file in bytes vs the length in characters, as unicode characters can...

libxml2: Stack Buffer Overflow in xmllint Interactive Shell Command Handling

A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare...

libxml2: Out-of-bounds Read in xmlSchemaIDCFillNodeTables

A flaw was found in the libxml2 library. A heap-based underflow can be triggered when a crafted XML document is validated against an XML schema with certain identity constraints or when a crafted XML schema is used, causing a crash to the application linked to the library and resulting in a denia...

libxml2: Memory Leak Leading to Local Denial of Service in xmllint Interactive Shell

A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where memory allocated for user input is not properly released under certain conditions. When a user submits input consisting only of whitespace, the program skips command execution but fails to fr...

libxml: Heap use after free (UAF) leads to Denial of service (DoS)

A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's...

libxml2: Integer Overflow in xmlBuildQName() Leads to Stack Buffer Overflow in libxml2

A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input...
