CVSS: 7.8EPSS: 2%CPEs: 7EXPL: 1CVE-2009-4272 – kernel: emergency route cache flushing leads to node deadlock
https://notcve.org/view.php?id=CVE-2009-4272
A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic. Cierto parche de Red Hat para net/ipv4/route.c en el kernel de Linux v2.6.18 en Red Hat Enterprise Linux (RHEL) v5 permite a atacantes remotos producir una denegación de servicio (punto muerto) a traves de paquetes manipulados que que fuerzan colisiones en la tabla de hash de enrutamiento IPv4, e inicia un enrutado de "emergencia" en el cual la cadena de hash es demasiado larga. NOTA: Esta vulnerabilidad esta relacionada con otra del cache de enrutamiento del kernel cuando el cache de enrutamiento del kernel esta desactivado, implicando un puntero no inicializado y panic. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=73e42897e8e5619eacb787d2ce69be12f47cfc21 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b6280b47a7a42970d098a3059f4ebe7e55e90d8d http://support.avaya.com/css/P8/documents/100073666 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.31 http://www.openwall.com/lists/oss-security/2010/01/20/1 http://www.openwall.com/lists/oss-security/2010/01/20/6 https://bugz • CWE-476: NULL Pointer Dereference CWE-667: Improper Locking •
