CVE-2012-2372

Status Candidate

Overview

The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB interface's own IP address, as demonstrated by rds-ping.

Red Hat Security Advisory 2012-1540-01 - These packages contain the Linux kernel. A race condition in the way asynchronous I/O and fallocate() interacted when using ext4 could allow a local, unprivileged user to obtain random data from a deleted file. A flaw in the way the Xen hypervisor implementation range checked guest provided addresses in the XENMEM_exchange hypercall could allow a malicious, para-virtualized guest administrator to crash the hypervisor or, potentially, escalate their privileges, allowing them to execute arbitrary code at the hypervisor level.

Ubuntu Security Notice 1530-1 - Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation. A remote NFS server (attacker) could exploit this flaw to cause a denial of service. Steve Grubb reported a flaw with Linux fscaps (file system base capabilities) when used to increase the permissions of a process. For application on which fscaps are in use a local attacker can disable address space randomization to make attacking the process with raised privileges easier. Various other issues were also addressed.

Red Hat Security Advisory 2012-0743-01
Posted Jun 18, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0743-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled, and that also have macvtap configured for at least one guest.
