CVSS: 4.9EPSS: 0%CPEs: 80EXPL: 2CVE-2009-2847 – Linux Kernel 2.6.31-rc5 - sigaltstack 4-Byte Stack Disclosure
https://notcve.org/view.php?id=CVE-2009-2847
The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 through 2.4.37 and 2.6 before 2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which allows local users to obtain sensitive information from the kernel stack via the sigaltstack function. La función do_sigaltstack en kernel/signal.c en el kernel de Linux 2.6 antes de 2.6.31-RC5, cuando se ejecuta en sistemas de 64 bits, no limpia algunos octetos de relleno de una estructura, lo que permite a usuarios locales obtener información sensible de la pila del núcleo a través de la función sigaltstack. • https://www.exploit-db.com/exploits/9352 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=0083fc2c50e6c5127c2802ad323adf8143ab7856 http://rhn.redhat.com/errata/RHSA-2009-1243.html http://secunia.com/advisories/36136 http://secunia.com/advisories/36501 http://secunia.com/advisories/36562 http://secunia.com/advisories/36759 http://secunia.com/advisories/37105 http://secunia.com/advisories/37471 http://www.exploit-db.com/exploits/9352 http://w •

cfg80211 in net/wireless/scan.c in the Linux kernel 2.6.30-rc1 and other versions before 2.6.31-rc6 allows remote attackers to cause a denial of service (crash) via a sequence of beacon frames in which one frame omits an SSID Information Element (IE) and the subsequent frame contains an SSID IE, which triggers a NULL pointer dereference in the cmp_ies function. NOTE: a potential weakness in the is_mesh function was also addressed, but the relevant condition did not exist in the code, so it is not a vulnerability. cfg80211 en el archivo net/wireless/scan.c en el kernel de Linux versión 2.6.30-rc1 y otras versiones anteriores a 2.6.31-rc6, permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) por medio de una secuencia de tramas beacon en los que una trama omite un Elemento de Información (IE) SSID y la trama posterior contiene un IE SSID, que desencadena una desreferencia de un puntero NULL en la función cmp_ies. NOTA: también se abordó una potencial debilidad en la función is_mesh, pero la condición relevante no existía en el código, por lo que no es una vulnerabilidad. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commitdiff%3Bh=cd3468bad96c00b5a512f551674f36776129520e http://jon.oberheide.org/files/cfg80211-remote-dos.c http://secunia.com/advisories/36278 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.30.5 http://www.openwall.com/lists/oss-security/2009/08/17/1 http://www.openwall.com/lists/oss-security/2009/08/17/2 http://www.securityfocus.com/bid/36052 • CWE-399: Resource Management Errors •

The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (OOPS) or possibly gain privileges via a CLOCK_MONOTONIC_RAW clock_nanosleep call that triggers a NULL pointer dereference.
