CVE-2025-32414 1 Xmlsoft 1 Libxml2 2025-04-23 N/A 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 N/A 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-2017-16931 1 Xmlsoft 1 Libxml2 2025-04-20 7.5 HIGH 9.8 CRITICAL
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 1 Xmlsoft 1 Libxml2 2025-04-20 5.0 MEDIUM 7.5 HIGH
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-2017-9049 1 Xmlsoft 1 Libxml2 2025-04-20 5.0 MEDIUM 7.5 HIGH
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 3 Debian, Oracle, Xmlsoft 3 Debian Linux, Solaris, Libxml2 2025-04-20 5.0 MEDIUM 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-2017-5969 1 Xmlsoft 1 Libxml2 2025-04-20 2.6 LOW 4.7 MEDIUM
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-2017-16932 1 Xmlsoft 1 Libxml2 2025-04-20 5.0 MEDIUM 7.5 HIGH
parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.
CVE-2017-8872 1 Xmlsoft 1 Libxml2 2025-04-20 6.4 MEDIUM 9.1 CRITICAL
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-2017-9050 1 Xmlsoft 1 Libxml2 2025-04-20 5.0 MEDIUM 7.5 HIGH
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-2017-9048 1 Xmlsoft 1 Libxml2 2025-04-20 5.0 MEDIUM 7.5 HIGH
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-2016-4447 8 Apple, Canonical, Debian and 5 more 12 Iphone Os, Itunes, Mac Os X and 9 more 2025-04-12 5.0 MEDIUM 7.5 HIGH
The xmlParseElementDecl function in parser.c in libxml2 before 2.9.4 allows context-dependent attackers to cause a denial of service (heap-based buffer underread and application crash) via a crafted file, involving xmlParseName.
CVE-2016-4658 2 Apple, Xmlsoft 5 Iphone Os, Mac Os X, Tvos and 2 more 2025-04-12 10.0 HIGH 9.8 CRITICAL
xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory corruption) via a crafted XML document.
CVE-2016-5131 8 Apple, Canonical, Debian and 5 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2025-04-12 6.8 MEDIUM 8.8 HIGH
Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.
CVE-2016-9318 3 Canonical, Xmlsec Project, Xmlsoft 3 Ubuntu Linux, Xmlsec, Libxml2 2025-04-12 4.3 MEDIUM 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-2015-8242 5 Apple, Canonical, Hp and 2 more 12 Iphone Os, Mac Os X, Tvos and 9 more 2025-04-12 5.8 MEDIUM N/A
The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.
CVE-2016-1834 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2025-04-12 9.3 HIGH 7.8 HIGH
Heap-based buffer overflow in the xmlStrncat function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.
CVE-2016-1833 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2025-04-12 4.3 MEDIUM 5.5 MEDIUM
The htmlCurrentChar function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
CVE-2016-1836 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2025-04-12 4.3 MEDIUM 5.5 MEDIUM
