| CVE-2019-9514 | Hig | 0.48 | 7.5 | 0.83 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the… | ||
| CVE-2019-9516 | Med | 0.47 | 6.5 | 0.56 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations… | ||
| CVE-2026-6732 | Med | 0.42 | 6.5 | 0.01 | Apr 23, 2026 | A flaw was found in libxml2. This vulnerability occurs when the library processes a specially crafted XML Schema Definition (XSD) validated document that includes an internal entity reference. An attacker could exploit this by providing a malicious document, leading to a type… | ||
| CVE-2025-6021 | Hig | 0.42 | 7.5 | 0.01 | Jun 12, 2025 | A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input. | ||
| CVE-2021-3541 | Med | 0.42 | 6.5 | 0.02 | Jul 9, 2021 | A flaw was found in libxml2. Exponential entity expansion attack its possible bypassing all existing protection mechanisms and leading to denial of service. | ||
| CVE-2021-3537 | Med | 0.39 | 5.9 | 0.03 | May 14, 2021 | 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… | ||
| CVE-2017-12613 | Hig | 0.39 | 7.1 | 0.02 | Oct 24, 2017 | When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a… | ||
| CVE-2026-0990 | Med | 0.38 | 5.9 | 0.01 | Jan 15, 2026 | A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent… | ||
| CVE-2023-6710 | Med | 0.38 | 5.4 | 0.02 | Dec 12, 2023 | A flaw was found in the mod_proxy_cluster in the Apache server. This issue may allow a malicious user to add a script in the 'alias' parameter in the URL to trigger the stored cross-site scripting (XSS) vulnerability. By adding a script on the alias parameter on the URL, it adds… | ||
| CVE-2018-17189 | Med | 0.36 | 5.3 | 0.20 | Jan 30, 2019 | In Apache HTTP server versions 2.4.37 and prior, by sending request bodies in a slow loris way to plain resources, the h2 stream for that request unnecessarily occupied a server thread cleaning up that incoming data. This affects only HTTP/2 (mod_http2) connections. | ||
| CVE-2016-9598 | Med | 0.35 | 6.5 | 0.01 | Aug 16, 2018 | 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. NOTE: this vulnerability exists because of a missing fix for CVE-2016-4483. | ||
| CVE-2016-9596 | Med | 0.35 | 6.5 | 0.01 | Aug 16, 2018 | libxml2, as used in Red Hat JBoss Core Services and when in recovery mode, allows context-dependent attackers to cause a denial of service (stack consumption) via a crafted XML document. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-3627. | ||
| CVE-2021-3688 | Med | 0.31 | 4.8 | 0.00 | Aug 26, 2022 | A flaw was found in Red Hat JBoss Core Services HTTP Server in all versions, where it does not properly normalize the path component of a request URL contains dot-dot-semicolon(s). This flaw could allow an attacker to access unauthorized information or possibly conduct further… | ||
| CVE-2026-3234 | Med | 0.28 | 4.3 | 0.00 | Mar 12, 2026 | A flaw was found in mod_proxy_cluster. This vulnerability, a Carriage Return Line Feed (CRLF) injection in the decodeenc() function, allows a remote attacker to bypass input validation. By injecting CRLF sequences into the cluster configuration, an attacker can corrupt the… | ||
| CVE-2019-0197 | Med | 0.28 | 4.2 | 0.09 | Jun 11, 2019 | A vulnerability was found in Apache HTTP Server 2.4.34 to 2.4.38. When HTTP/2 was enabled for a http: host or H2Upgrade was enabled for h2 on a https: host, an Upgrade request from http/1.1 to http/2 that was not the first request on a connection could lead to a misconfiguration… | ||
| CVE-2026-0989 | Low | 0.24 | 3.7 | 0.00 | Jan 15, 2026 | A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested directives. Specially crafted or overly complex schemas can cause excessive… | ||
| CVE-2026-0992 | Low | 0.19 | 2.9 | 0.00 | Jan 15, 2026 | A flaw was found in the libxml2 library. This uncontrolled resource consumption vulnerability occurs when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this by supplying crafted… | ||
| CVE-2025-6170 | Low | 0.09 | 2.5 | 0.00 | Jun 16, 2025 | A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful… | ||
| CVE-2021-3517 | Hig | 0.01 | 8.6 | 0.08 | May 19, 2021 | 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… | ||
| CVE-2021-3516 | Hig | 0.00 | 7.8 | 0.02 | Jun 1, 2021 | There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability. |
