| libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251. | |||||
| CVE-2018-14404 | 3 Canonical, Debian, Xmlsoft | 3 Ubuntu Linux, Debian Linux, Libxml2 | 2026-06-17 | 5.0 MEDIUM | 6.5 MEDIUM |
| A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application. | |||||
| CVE-2017-9050 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 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 | 2026-06-17 | 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 | 2026-06-17 | 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 | 2026-06-17 | 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-2017-8872 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 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-2017-7376 | 3 Debian, Google, Xmlsoft | 3 Debian Linux, Android, Libxml2 | 2026-06-17 | 10.0 HIGH | 9.8 CRITICAL |
| Buffer overflow in libxml2 allows remote attackers to execute arbitrary code by leveraging an incorrect limit for port values when handling redirects. | |||||
| CVE-2017-7375 | 3 Debian, Google, Xmlsoft | 3 Debian Linux, Android, Libxml2 | 2026-06-17 | 7.5 HIGH | 9.8 CRITICAL |
| A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable). | |||||
| CVE-2017-5969 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 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-2017-5130 | 3 Debian, Google, Xmlsoft | 3 Debian Linux, Chrome, Libxml2 | 2026-06-17 | 6.8 MEDIUM | 8.8 HIGH |
| An integer overflow in xmlmemory.c in libxml2 before 2.9.5, as used in Google Chrome prior to 62.0.3202.62 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted XML file. | |||||
| CVE-2017-18258 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 4.3 MEDIUM | 6.5 MEDIUM |
| The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file. | |||||
| CVE-2017-16932 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 5.0 MEDIUM | 7.5 HIGH |
| parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities. | |||||
| CVE-2017-16931 | 1 Xmlsoft | 1 Libxml2 | 2026-06-17 | 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-2017-15412 | 4 Debian, Google, Redhat and 1 more | 6 Debian Linux, Chrome, Enterprise Linux Desktop and 3 more | 2026-06-17 | 6.8 MEDIUM | 8.8 HIGH |
| Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. | |||||
