|---|---|---|---|---|---|
| CVE-2022-29824 | 2 Fedoraproject, Xmlsoft | 3 Fedora, Libxml2, Libxslt | 2022-05-18 | 4.3 MEDIUM | 6.5 MEDIUM |
| In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2's buffer functions, for example libxslt through 1.1.35, is affected as well. | |||||

| CVE-2021-3518 | 6 Debian, Fedoraproject, Netapp and 3 more | 16 Debian Linux, Fedora, Active Iq Unified Manager and 13 more | 2022-04-20 | 6.8 MEDIUM | 8.8 HIGH |
| 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 | 2022-04-20 | 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-2021-3537 | 6 Debian, Fedoraproject, Netapp and 3 more | 17 Debian Linux, Fedora, Active Iq Unified Manager and 14 more | 2022-04-20 | 4.3 MEDIUM | 5.9 MEDIUM |
| A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability. | |||||

| CVE-2017-5969 | 1 Xmlsoft | 1 Libxml2 | 2022-04-08 | 2.6 LOW | 4.7 MEDIUM |
| ** DISPUTED ** 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-2016-9318 | 3 Canonical, Xmlsec Project, Xmlsoft | 3 Ubuntu Linux, Xmlsec, Libxml2 | 2022-04-08 | 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-2017-5130 | 3 Debian, Google, Xmlsoft | 3 Debian Linux, Chrome, Libxml2 | 2022-04-08 | 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-2017-16932 | 1 Xmlsoft | 1 Libxml2 | 2022-04-08 | 5.0 MEDIUM | 7.5 HIGH |
| parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities. | |||||

| 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-2019-19956 | 7 Canonical, Debian, Fedoraproject and 4 more | 12 Ubuntu Linux, Debian Linux, Fedora and 9 more | 2021-07-21 | 5.0 MEDIUM | 7.5 HIGH |
| xmlParseBalancedChunkMemoryRecover in parser.c in libxml2 before 2.9.10 has a memory leak related to newDoc->oldNs. | |||||
| CVE-2017-16931 | 1 Xmlsoft | 1 Libxml2 | 2021-07-20 | 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 | 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-2017-9050 | 1 Xmlsoft | 1 Libxml2 | 2021-06-29 | 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 | 2021-06-29 | 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 | 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. | |||||
