xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs. | |||||
CVE-2017-9050 | 1 Xmlsoft | 1 Libxml2 | 2023-11-07 | 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-2017-9049 | 1 Xmlsoft | 1 Libxml2 | 2023-11-07 | 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-2017-9048 | 1 Xmlsoft | 1 Libxml2 | 2023-11-07 | 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-2017-9047 | 1 Xmlsoft | 1 Libxml2 | 2023-11-07 | 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-2017-16932 | 1 Xmlsoft | 1 Libxml2 | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities. | |||||

libxml2, as used in Red Hat JBoss Core Services and when in recovery mode, allows context-dependent attackers to cause a denial of service (stack consumption) via a crafted XML document. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-3627. | |||||
CVE-2016-5131 | 8 Apple, Canonical, Debian and 5 more | 14 Iphone Os, Mac Os X, Tvos and 11 more | 2023-11-07 | 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-2016-4483 | 3 Debian, Oracle, Xmlsoft | 3 Debian Linux, Solaris, Libxml2 | 2023-11-07 | 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-2015-6838 | 2 Php, Xmlsoft | 2 Php, Libxml2 | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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 | 2 Php, Xmlsoft | 2 Php, Libxml2 | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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-2013-2877 | 2 Google, Xmlsoft | 2 Chrome, Libxml2 | 2023-11-07 | 5.0 MEDIUM | N/A |
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state. | |||||
CVE-2013-0339 | 4 Canonical, Debian, Suse and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Enterprise Server and 1 more | 2023-11-07 | 6.8 MEDIUM | N/A |
libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because libxml2 already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed and each affected application would need its own CVE. | |||||
CVE-2012-5134 | 3 Apple, Google, Xmlsoft | 3 Iphone Os, Chrome, Libxml2 | 2023-11-07 | 6.8 MEDIUM | N/A |
Heap-based buffer underflow in the xmlParseAttValueComplex function in parser.c in libxml2 2.9.0 and earlier, as used in Google Chrome before 23.0.1271.91 and other products, allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted entities in an XML document. | |||||
CVE-2012-2871 | 3 Apple, Google, Xmlsoft | 3 Iphone Os, Chrome, Libxml2 | 2023-11-07 | 6.8 MEDIUM | N/A |
libxml2 2.9.0-rc1 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly support a cast of an unspecified variable during handling of XSL transforms, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted document, related to the _xmlNs data structure in include/libxml/tree.h. | |||||
CVE-2023-29469 | 2 Debian, Xmlsoft | 2 Debian Linux, Libxml2 | 2023-06-01 | N/A | 6.5 MEDIUM |
An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value). | |||||
CVE-2008-3529 | 4 Apple, Canonical, Debian and 1 more | 6 Iphone Os, Mac Os X, Safari and 3 more | 2023-02-13 | 10.0 HIGH | N/A |
Heap-based buffer overflow in the xmlParseAttValueComplex function in parser.c in libxml2 before 2.7.0 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a long XML entity name. | |||||
CVE-2009-2414 | 1 Xmlsoft | 2 Libxml, Libxml2 | 2023-02-13 | 4.3 MEDIUM | N/A |
Stack consumption vulnerability in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allows context-dependent attackers to cause a denial of service (application crash) via a large depth of element declarations in a DTD, related to a function recursion, as demonstrated by the Codenomicon XML fuzzing framework. | |||||
CVE-2015-7500 | 6 Apple, Canonical, Debian and 3 more | 13 Iphone Os, Mac Os X, Tvos and 10 more | 2023-02-13 | 5.0 MEDIUM | N/A |
The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags. |
