| There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability. | |||||
| CVE-2021-3517 | 6 Debian, Fedoraproject, Netapp and 3 more | 26 Debian Linux, Fedora, Active Iq Unified Manager and 23 more | 2022-07-25 | 7.5 HIGH | 8.6 HIGH |
| There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application. | |||||
| CVE-2020-7595 | 7 Canonical, Debian, Fedoraproject and 4 more | 32 Ubuntu Linux, Debian Linux, Fedora and 29 more | 2022-07-25 | 5.0 MEDIUM | 7.5 HIGH |

| CVE-2022-2309 | 2 Lxml, Xmlsoft | 2 Lxml, Libxml2 | 2022-07-13 | 5.0 MEDIUM | 7.5 HIGH |
| NULL Pointer Dereference allows attackers to cause a denial of service (or application crash). This only applies when lxml is used together with libxml2 2.9.10 through 2.9.14. libxml2 2.9.9 and earlier are not affected. It allows triggering crashes through forged input data, given a vulnerable code sequence in the application. The vulnerability is caused by the iterwalk function (also used by the canonicalize function). Such code shouldn't be in wide-spread use, given that parsing + iterwalk would usually be replaced with the more efficient iterparse function. However, an XML converter that serialises to C14N would also be vulnerable, for example, and there are legitimate use cases for this code sequence. If untrusted input is received (also remotely) and processed via iterwalk function, a crash can be triggered. | |||||

| CVE-2017-9048 | 1 Xmlsoft | 1 Libxml2 | 2021-06-29 | 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 | 2021-06-29 | 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-2016-4483 | 3 Debian, Oracle, Xmlsoft | 3 Debian Linux, Solaris, Libxml2 | 2021-06-29 | 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-2018-14404 | 3 Canonical, Debian, Xmlsoft | 3 Ubuntu Linux, Debian Linux, Libxml2 | 2020-09-10 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
