| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2022-29824 | 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. | [email protected] | 6.5 | 3.40% | 2022-05-02 | 2026-06-17 |

| CVE-2021-3518 | 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. | [email protected] | 8.8 | 3.65% | 2021-05-18 | 2026-06-17 |
| CVE-2021-3537 | 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.

| CVE-2017-15412 | 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. | [email protected] | 8.8 | 2.96% | 2018-08-28 | 2026-06-16 |
| CVE-2018-14567 | 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. | [email protected] | 6.5 | 4.30% | 2018-08-16 | 2026-06-16 |
| CVE-2016-9598 | libxml2, as used in Red Hat JBoss Core Services, allows context-dependent attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted XML document.

| CVE-2016-9597 | It was found that Red Hat JBoss Core Services erratum RHSA-2016:2957 for CVE-2016-3705 did not actually include the fix for the issue found in libxml2, making it vulnerable to a Denial of Service attack due to a Stack Overflow. This is a regression CVE for the same issue as CVE-2016-3705. | [email protected] | 7.5 | 4.36% | 2018-07-30 | 2026-06-16 |
| CVE-2018-14404 | 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. | [email protected] | 6.5 | 3.68% | 2018-07-19 | 2026-06-16 |
| CVE-2017-18258 | 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. | [email protected] | 6.5 | 2.71% | 2018-04-08 | 2026-06-16 |
| CVE-2018-9251 | The xz_decomp function in xzlib.c in 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. | [email protected] | 5.3 | 2.44% | 2018-04-03 | 2026-06-16 |

| CVE-2017-7375 | 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). | [email protected] | 9.8 | 2.69% | 2018-02-19 | 2026-06-16 |
