CVSS: 4.9EPSS: 0%CPEs: 67EXPL: 2CVE-2012-3375 – Linux Kernel 3.2.24 - 'fs/eventpoll.c' Local Denial of Service
https://notcve.org/view.php?id=CVE-2012-3375
The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083. La llamada al sistema epoll_ctl en fs/eventpoll.c en el Kernel de Linux anteriores a v3.2.24 no gestiona de forma adecuada errores ELOOP en operaciones EPOLL_CTL_ADD, lo que permite a usuarios locales provocar una denegación de servicio (consumo de descriptores de ficheros y caída del sistema) a través de una aplicación manipulada que intenta crear una dependencia epoll circular. NOTA: esta vulnerabilidad existe debido a una resolución incorrecta de CVE-2011-1083. The Linux kernel suffers from a local denial of service vulnerability in fs/eventpoll.c. • https://www.exploit-db.com/exploits/19605 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=13d518074a952d33d47c428419693f63389547e9 http://secunia.com/advisories/51164 http://ubuntu.com/usn/usn-1529-1 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.2.24 http://www.openwall.com/lists/oss-security/2012/07/04/2 http://www.securitytracker.com/id?1027237 https://bugzilla.redhat.com/show_bug.cgi?id=837502 https://downloads.avaya.com& •

The rose_parse_ccitt function in net/rose/rose_subr.c in the Linux kernel before 2.6.39 does not validate the FAC_CCITT_DEST_NSAP and FAC_CCITT_SRC_NSAP fields, which allows remote attackers to (1) cause a denial of service (integer underflow, heap memory corruption, and panic) via a small length value in data sent to a ROSE socket, or (2) conduct stack-based buffer overflow attacks via a large length value in data sent to a ROSE socket. La función rose_parse_ccitt en la net/rose/rose_subr.c en el kernel de Linux en versiones anteriores a la v2.6.39 no valida los campos FAC_CCITT_DEST_NSAP y FAC_CCITT_SRC_NSAP, lo que permite a atacantes remotos (1) provocar una denegación de servicio (desbordamiento de enteros, corrupción de memoria dinámica, y 'panic' del kernel) a través de un valor de longitud pequeña en los datos enviados a un 'socket' ROSE, o (2) llevar a cabo ataques de desbordamiento de pila basados ??en buffer a través de un valor de longitud demasiado grande en los datos enviados a un 'socket' ROSE. • http://ftp.osuosl.org/pub/linux/kernel/v2.6/ChangeLog-2.6.39 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=be20250c13f88375345ad99950190685eda51eb8 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://www.openwall.com/lists/oss-security/2011/12/28/2 https://bugzilla.redhat.com/show_bug.cgi?id=770777 https://github.com/torvalds/linux/commit/be20250c13f88375345ad99950190685eda51eb8 • CWE-20: Improper Input Validation •
