https://notcve.org/view.php?id=CVE-2021-43519
Stack overflow in lua_resume of ldo.c in Lua Interpreter 5.1.0~5.4.4 allows attackers to perform a Denial of Service via a crafted script file. UN desbordamiento de pila en la función lua_resume del archivo ldo.c en Lua Interpreter versiones 5.1.0~5.4.4, permite a atacantes llevar a cabo una Denegación de Servicio por medio de un archivo de script diseñado A stack overflow issue was discovered in Lua in the lua_resume() function of 'ldo.c'. This flaw allows a local attacker to pass a specially crafted file to the Lua Interpreter, causing a crash that leads to a denial of service. • http://lua-users.org/lists/lua-l/2021-10/msg00123.html http://lua-users.org/lists/lua-l/2021-11/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/C7XHFYHGSZKL53VCLSJSAJ6VMFGAIXKO https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/P3EMGAQ5Y6GXJLY4K5DUOOEQT4MZ4J4F https://access.redhat.com/security/cve/CVE-2021-43519 https://bugzilla.redhat.com/show_bug.cgi?id=2047672 • CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •

An issue was discovered in Prosody before 0.11.9. It does not use a constant-time algorithm for comparing certain secret strings when running under Lua 5.2 or later. This can potentially be used in a timing attack to reveal the contents of secret strings to an attacker. Se detectó un problema en Prosody versiones anteriores a 0.11.9. No utiliza un algoritmo de tiempo constante para comparar determinadas cadenas secretas cuando se ejecuta bajo Lua versiones 5.2 o posteriores. • http://www.openwall.com/lists/oss-security/2021/05/13/1 http://www.openwall.com/lists/oss-security/2021/05/14/2 https://blog.prosody.im/prosody-0.11.9-released https://lists.debian.org/debian-lts-announce/2021/06/msg00016.html https://lists.debian.org/debian-lts-announce/2021/06/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6MFFBZWXKPZEVZNQSVJNCUE7WRF3T7DG https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedora • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
