CVE-2015-3415 – sqlite: invalid free() in src/vdbe.c

https://notcve.org/view.php?id=CVE-2015-3415

The sqlite3VdbeExec function in vdbe.c in SQLite before 3.8.9 does not properly implement comparison operators, which allows context-dependent attackers to cause a denial of service (invalid free operation) or possibly have unspecified other impact via a crafted CHECK clause, as demonstrated by CHECK(0&O>O) in a CREATE TABLE statement. La función sqlite3VdbeExec en vdbe.c en SQLite anterior a 3.8.9 no implementa correctamente los operadores de comparaciones, lo que permite a atacantes dependientes de contexto causar una denegación de servicio (operación de liberación inválida) o posiblemente tener otro impacto no especificado a través de una clausula CHECK manipulada, tal y como fue demostrado por CHECK(0&O>O) en una declaración CREATE TABLE. It was found that SQLite's sqlite3VdbeExec() function did not properly implement comparison operators. A local attacker could submit a specially crafted CHECK statement that would crash the SQLite process, or have other unspecified impacts. • http://lists.apple.com/archives/security-announce/2015/Sep/msg00005.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00008.html http://rhn.redhat.com/errata/RHSA-2015-1635.html http://seclists.org/fulldisclosure/2015/Apr/31 http://www.debian.org/security/2015/dsa-3252 http://www.mandriva.com/security/advisories?name=MDVSA-2015:217 http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/topics/security/bulletinapr2016-295 • CWE-404: Improper Resource Shutdown or Release •
