CVE-2011-0006

La función ima_lsm_rule_init en security/integrity/ima/ima_policy.c en versiones del kernel de Linux anteriores a v2.6.37, cuando 'Linux Security Modules' (LSM) está desactivado, permite a usuarios locales eludir las reglas de 'Integrity Measurement Architecture' (IMA) en determinadas circunstancias aprovechándose de la inclusión de una regla IMA a LSM.

Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's handling of IPv4 icmp packets. A remote user could exploit this to cause a denial of service. Vegard Nossum discovered a leak in the kernel's inotify_init() system call. A local, unprivileged user could exploit this to cause a denial of service. An error was discovered in the kernel's handling of CUSE (Character device in Userspace). A local attacker might exploit this flaw to escalate privilege, if access to /dev/cuse has been modified to allow non-root users. Various other issues were also addressed.
