Oracle Linux 5 : Oracle / Linux / 5.7 / kernel (ELSA-2011-1065)

high Nessus Plugin ID 181031


The remote Oracle Linux host is missing one or more security updates.


The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-1065 advisory.

- The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service (host crash) by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread. (CVE-2011-1780)

- The qdisc_notify function in net/sched/sch_api.c in the Linux kernel before 2.6.35 does not prevent tc_fill_qdisc function calls referencing builtin (aka CQ_F_BUILTIN) Qdisc structures, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a crafted call. (CVE-2011-2525)

- The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Update the affected packages.
