CVE-2022-40303 4 Apple, Netapp, Redhat and 1 more 25 Ipados, Iphone Os, Macos and 22 more 2025-04-29 7.5 High
An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault.
CVE-2022-40304 4 Apple, Netapp, Redhat and 1 more 25 Ipados, Iphone Os, Macos and 22 more 2025-04-28 7.8 High
An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked.
CVE-2025-32414 1 Xmlsoft 1 Libxml2 2025-04-23 5.6 Medium
In libxml2 before 2.13.8 and 2.14.x before 2.14.2, out-of-bounds memory access can occur in the Python API (Python bindings) because of an incorrect return value. This occurs in xmlPythonFileRead and xmlPythonFileReadRaw because of a difference between bytes and characters.
CVE-2025-32415 1 Xmlsoft 1 Libxml2 2025-04-23 2.9 Low
In libxml2 before 2.13.8 and 2.14.x before 2.14.2, xmlSchemaIDCFillNodeTables in xmlschemas.c has a heap-based buffer under-read. To exploit this, a crafted XML document must be validated against an XML schema with certain identity constraints, or a crafted XML schema must be used.
CVE-2017-9049 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for libxml2 Bug 759398.
CVE-2017-8872 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
The htmlParseTryOrFinish function in HTMLparser.c in libxml2 2.9.4 allows attackers to cause a denial of service (buffer over-read) or information disclosure.
CVE-2017-16931 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
parser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name.
CVE-2017-9047 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.
CVE-2017-9048 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer overflow. The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size. This vulnerability causes programs that use libxml2, such as PHP, to crash.
CVE-2017-9050 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a heap-based buffer over-read in the xmlDictAddString function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash. This vulnerability exists because of an incomplete fix for CVE-2016-1839.
CVE-2016-4483 4 Debian, Oracle, Redhat and 1 more 4 Debian Linux, Solaris, Jboss Core Services and 1 more 2025-04-20 7.5 High
The xmlBufAttrSerializeTxtContent function in xmlsave.c in libxml2 allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a non-UTF-8 attribute value, related to serialization. NOTE: this vulnerability may be a duplicate of CVE-2016-3627.
CVE-2017-16932 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.
CVE-2017-5969 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser.
CVE-2014-3660 5 Apple, Canonical, Debian and 2 more 5 Mac Os X, Ubuntu Linux, Debian Linux and 2 more 2025-04-12 N/A
parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.
CVE-2015-8317 5 Canonical, Debian, Hp and 2 more 11 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 8 more 2025-04-12 N/A
The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
CVE-2016-9318 4 Canonical, Redhat, Xmlsec Project and 1 more 4 Ubuntu Linux, Jboss Core Services, Xmlsec and 1 more 2025-04-12 5.5 Medium
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document.
CVE-2015-8035 5 Apple, Canonical, Debian and 2 more 10 Iphone Os, Mac Os X, Tvos and 7 more 2025-04-12 N/A
The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.
CVE-2015-7941 3 Canonical, Redhat, Xmlsoft 4 Ubuntu Linux, Enterprise Linux, Jboss Enterprise Web Server and 1 more 2025-04-12 N/A
libxml2 2.9.2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function in parser.c, as demonstrated by non-terminated entities.
CVE-2015-6837 3 Php, Redhat, Xmlsoft 3 Php, Rhel Software Collections, Libxml2 2025-04-12 N/A
The xsl_ext_function_php function in ext/xsl/xsltprocessor.c in PHP before 5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13, when libxml2 before 2.9.2 is used, does not consider the possibility of a NULL valuePop return value before proceeding with a free operation during initial error checking, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted XML document, a different vulnerability than CVE-2015-6838.
CVE-2015-7498 5 Canonical, Debian, Hp and 2 more 11 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 8 more 2025-04-12 N/A
Heap-based buffer overflow in the xmlParseXmlDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors related to extracting errors after an encoding conversion failure.
