CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 1CVE-2009-3238 – kernel: random: add robust get_random_u32, remove weak get_random_int
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) •

pam-auth-update for PAM, as used in Ubuntu 8.10 and 9.4, and Debian GNU/Linux, does not properly handle an "empty selection" for system authentication modules in certain rare configurations, which causes any attempt to be successful and allows remote attackers to bypass authentication. pam-auth-update para PAM, tal y como se utiliza Ubuntu v8.10 y v9.4, y Debian GNU/Linux, no gestiona adecuadamente una "selección vacía" para los módulos de autenticacion del sistema en ciertas configuraciones poco frecuentes, lo que lleva a que cualquier intento de autenticación tenga exito lo que permite a atacantes remotos evitar este paso. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=519927 http://secunia.com/advisories/36620 http://www.openwall.com/lists/oss-security/2009/09/08/7 http://www.securityfocus.com/bid/36306 https://launchpad.net/bugs/410171 https://usn.ubuntu.com/828-1 • CWE-287: Improper Authentication •
