CVE-2008-4409 1 Xmlsoft 1 Libxml2 2026-04-23 5.0 MEDIUM N/A
libxml2 2.7.0 and 2.7.1 does not properly handle "predefined entities definitions" in entities, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash), as demonstrated by use of xmllint on a certain XML document, a different vulnerability than CVE-2003-1564 and CVE-2008-3281.
CVE-2008-3529 4 Apple, Canonical, Debian and 1 more 6 Iphone Os, Mac Os X, Safari and 3 more 2026-04-23 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-2008-2935 1 Xmlsoft 1 Libxslt 2026-04-23 7.5 HIGH N/A
Multiple heap-based buffer overflows in the rc4 (1) encryption (aka exsltCryptoRc4EncryptFunction) and (2) decryption (aka exsltCryptoRc4DecryptFunction) functions in crypto.c in libexslt in libxslt 1.1.8 through 1.1.24 allow context-dependent attackers to execute arbitrary code via an XML file containing a long string as "an argument in the XSL input."
CVE-2008-4226 1 Xmlsoft 1 Libxml 2026-04-23 10.0 HIGH N/A
Integer overflow in the xmlSAX2Characters function in libxml2 2.7.2 allows context-dependent attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a large XML document.
CVE-2003-1564 1 Xmlsoft 1 Libxml2 2026-04-16 9.3 HIGH 6.5 MEDIUM
libxml2, possibly before 2.5.0, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka the "billion laughs attack."
CVE-2004-0110 2 Sgi, Xmlsoft 3 Propack, Libxml, Libxml2 2026-04-16 7.5 HIGH N/A
Buffer overflow in the (1) nanohttp or (2) nanoftp modules in XMLSoft Libxml 2 (Libxml2) 2.6.0 through 2.6.5 allow remote attackers to execute arbitrary code via a long URL.
CVE-2004-0989 5 Redhat, Trustix, Ubuntu and 2 more 6 Fedora Core, Secure Linux, Ubuntu Linux and 3 more 2026-04-16 10.0 HIGH N/A
Multiple buffer overflows in libXML 2.6.12 and 2.6.13 (libxml2), and possibly other versions, may allow remote attackers to execute arbitrary code via (1) a long FTP URL that is not properly handled by the xmlNanoFTPScanURL function, (2) a long proxy URL containing FTP data that is not properly handled by the xmlNanoFTPScanProxy function, and other overflows related to manipulation of DNS length values, including (3) xmlNanoFTPConnect, (4) xmlNanoHTTPConnectHost, and (5) xmlNanoHTTPConnectHost.
CVE-2019-20388 6 Debian, Fedoraproject, Netapp and 3 more 31 Debian Linux, Fedora, Cloud Backup and 28 more 2025-12-17 5.0 MEDIUM 7.5 HIGH
xmlSchemaPreRun in xmlschemas.c in libxml2 2.9.10 allows an xmlSchemaValidateStream memory leak.
CVE-2017-7375 3 Debian, Google, Xmlsoft 3 Debian Linux, Android, Libxml2 2025-12-03 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-2017-5130 3 Debian, Google, Xmlsoft 3 Debian Linux, Chrome, Libxml2 2025-12-03 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-2018-14404 3 Canonical, Debian, Xmlsoft 3 Ubuntu Linux, Debian Linux, Libxml2 2025-12-03 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-2019-19956 7 Canonical, Debian, Fedoraproject and 4 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2025-12-03 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-2020-7595 7 Canonical, Debian, Fedoraproject and 4 more 32 Ubuntu Linux, Debian Linux, Fedora and 29 more 2025-12-03 5.0 MEDIUM 7.5 HIGH
xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation.
CVE-2021-3517 6 Debian, Fedoraproject, Netapp and 3 more 29 Debian Linux, Fedora, Active Iq Unified Manager and 26 more 2025-12-02 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-2024-40896 2 Netapp, Xmlsoft 14 H300s, H300s Firmware, H410c and 11 more 2025-11-25 N/A 9.1 CRITICAL
In libxml2 2.11 before 2.11.9, 2.12 before 2.12.9, and 2.13 before 2.13.3, the SAX parser can produce events for external entities even if custom SAX handlers try to override entity content (by setting "checked"). This makes classic XXE attacks possible.
CVE-2024-34459 1 Xmlsoft 1 Libxml2 2025-11-04 N/A 7.5 HIGH
An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c.
CVE-2022-2309 3 Fedoraproject, Lxml, Xmlsoft 3 Fedora, Lxml, Libxml2 2025-11-04 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-2016-3709 1 Xmlsoft 1 Libxml2 2025-11-04 N/A 6.1 MEDIUM
Possible cross-site scripting vulnerability in libxml after commit 960f0e2.
CVE-2025-27113 1 Xmlsoft 1 Libxml2 2025-11-03 N/A 2.9 LOW
libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a NULL pointer dereference in xmlPatMatch in pattern.c.
CVE-2025-24928 2 Netapp, Xmlsoft 16 Active Iq Unified Manager, H300s, H300s Firmware and 13 more 2025-11-03 N/A 7.8 HIGH
libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a stack-based buffer overflow in xmlSnprintfElements in valid.c. To exploit this, DTD validation must occur for an untrusted document or untrusted DTD. NOTE: this is similar to CVE-2017-9047.
