CVE-2012-3518

https://notcve.org/view.php?id=CVE-2012-3518

The networkstatus_parse_vote_from_string function in routerparse.c in Tor before 0.2.2.38 does not properly handle an invalid flavor name, which allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted (1) vote document or (2) consensus document. La función networkstatus_parse_vote_from_string en routerparse.c en Tor anterior a v0.2.2.38 no maneja adecuadamente un (flavor name), lo cual podría permitir a atacantes remotos causar una denegación de servicio (lectura fuera de rango y caída del demonio) a través de (1) un documento de voto o (2) un documento de consenso manipulados. • http://lists.opensuse.org/opensuse-updates/2012-08/msg00048.html http://openwall.com/lists/oss-security/2012/08/21/6 http://secunia.com/advisories/50583 http://security.gentoo.org/glsa/glsa-201301-03.xml https://gitweb.torproject.org/tor.git/commit/55f635745afacefffdaafc72cc176ca7ab817546 https://gitweb.torproject.org/tor.git/commit/57e35ad3d91724882c345ac709666a551a977f0f https://lists.torproject.org/pipermail/tor-announce/2012-August/000086.html https://trac.torproject.org/projects/tor/ticket/6530 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
