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-2017-9047 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-2017-9050 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-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-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-2017-9048 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-2017-9049 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-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-2017-16931 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-2017-16932 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-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-2015-6838 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 after the principal argument loop, 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-2015-6837.
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.
