CVSS: 5.5EPSS: 0%CPEs: 18EXPL: 1CVE-2020-15358 – sqlite: heap-based buffer overflow in multiSelectOrderBy due to mishandling of query-flattener optimization in select.c
https://notcve.org/view.php?id=CVE-2020-15358
In SQLite before 3.32.3, select.c mishandles query-flattener optimization, leading to a multiSelectOrderBy heap overflow because of misuse of transitive properties for constant propagation. En SQLite versiones anteriores a 3.32.3, el archivo select.c maneja inapropiadamente la optimización query-flattener, conllevando a un desbordamiento de la pila de multiSelectOrderBy debido al uso inapropiado de las propiedades transitivas para la propagación constante A heap buffer overflow was found in SQLite in the query flattening optimization technique. This flaw allows an attacker to execute SQL statements to crash the application, resulting in a denial of service. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 http://seclists.org/fulldisclosure/2021/Feb/14 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://security.gentoo.org/glsa/202007-26 https://security.netapp.com/advisory/ntap-20200709-0001 https://support.apple.com/kb/HT211843 https://support.apple.com/kb/HT211844 https • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-11080 – Denial of service in nghttp2
https://notcve.org/view.php?id=CVE-2020-11080
In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the number of settings entries are large (e.g., > 32), then drop the connection. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html https://github.com/nghttp2/nghttp2/commit/336a98feb0d56b9ac54e12736b18785c27f75090 https://github.com/nghttp2/nghttp2/commit/f8da73bd042f810f34d19f9eae02b46d870af394 https://github.com/nghttp2/nghttp2/security/advisories/GHSA-q5wr-xfw9-q7xr https://lists.debian.org/debian-lts-announce/2021/10/msg00011.html https://lists.debian.org/debian-lts-announce/2023/10/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject& • CWE-400: Uncontrolled Resource Consumption CWE-707: Improper Neutralization CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 8%CPEs: 38EXPL: 1CVE-2020-1967 – Segmentation fault in SSL_check_chain
https://notcve.org/view.php?id=CVE-2020-1967
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. • https://github.com/irsl/CVE-2020-1967 http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00011.html http://packetstormsecurity.com/files/157527/OpenSSL-signature_algorithms_cert-Denial-Of-Service.html http://seclists.org/fulldisclosure/2020/May/5 http://www.openwall.com/lists/oss-security/2020/04/22/2 https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=eb563247aef3e83dda7679c43f9649270462e5b1 https:/&# • CWE-476: NULL Pointer Dereference •
