The sg_build_indirect function in drivers/scsi/sg.c in Linux kernel 2.6.28-rc1 through 2.6.31-rc8 uses an incorrect variable when accessing an array, which allows local users to cause a denial of service (kernel OOPS and NULL pointer dereference), as demonstrated by using xcdroast to duplicate a CD. NOTE: this is only exploitable by users who can open the cdrom device. La función sg_build_indirect en drivers/scsi/sg.c en el kernel de linux v 2.6.28-rc1 a la v2.6.31-rc8 emplea una variable incorrecta cuando accede a una matriz, lo que permite a usuarios locales provocar una denegación de servicio (Kernel OOPS y una deferencia a puntero NULL), como se ha demostrado usando xcdroast para duplicar un CD. NOTA: esto es explotable únicamente por usuarios que pueden abrir la unidad de CD. • http://lkml.org/lkml/2009/9/3/1 http://lkml.org/lkml/2009/9/3/107 http://secunia.com/advisories/37105 http://www.openwall.com/lists/oss-security/2009/09/03/4 http://www.ubuntu.com/usn/USN-852-1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2009-3238
The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time." La función get_random_int de drivers/char/random.c en el kernel de Linux anterior a v2.6.30, produce números que nos son suficientemente aleatorios, esto permite a los atacantes predecir el valor devuelto y permite que se puedan superar los mecanismos de protección basados en la aleatoriedad, a través de vectores que eleven la tendencia de la función a "devolver el mismo valor una y otra vez durante largos periodos de tiempo". • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8a0a9bd4db63bc45e3017bedeafbd88d0eb84d02 http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://patchwork.kernel.org/patch/21766 http://secunia.com/advisories/37105 http://secunia.com/advisories/37351 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.30 http://www.redhat.com/support/errata/RHSA-2009& • CWE-330: Use of Insufficiently Random Values CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) •
