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 •
