Multiple race conditions in the madvise_remove function in mm/madvise.c in the Linux kernel before 3.4.5 allow local users to cause a denial of service (use-after-free and system crash) via vectors involving a (1) munmap or (2) close system call.

Updated kernel-rt packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise MRG 2.2.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* A flaw was found in the way Netlink messages without SCM_CREDENTIALS (used for authentication) data set were handled. When not explicitly set, the data was sent but with all values set to 0, including the process ID and user ID, causing the Netlink message to appear as if it were sent with root privileges. A local, unprivileged user could use this flaw to send spoofed Netlink messages to an application, possibly resulting in the application performing privileged operations if it relied on SCM_CREDENTIALS data for the authentication of Netlink messages. (CVE-2012-3520, Important)

* A race condition was found in the way asynchronous I/O and fallocate() interacted when using the ext4 file system. A local, unprivileged user could use this flaw to expose random data from an extent whose data blocks have not yet been written, and thus contain data from a deleted file. (CVE-2012-4508, Important)

* A use-after-free flaw was found in the Linux kernel's memory management subsystem in the way quota handling for huge pages was performed. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges.
(CVE-2012-2133, Moderate)

* A use-after-free flaw was found in the madvise() system call implementation in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2012-3511, Moderate)

* A divide-by-zero flaw was found in the TCP Illinois congestion control algorithm implementation in the Linux kernel. If the TCP Illinois congestion control algorithm were in use (the sysctl net.ipv4.tcp_congestion_control variable set to 'illinois'), a local, unprivileged user could trigger this flaw and cause a denial of service. (CVE-2012-4565, Moderate)

* An information leak flaw was found in the uname() system call implementation in the Linux kernel. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space by setting the UNAME26 personality and then calling the uname() system call.
(CVE-2012-0957, Low)

* Buffer overflow flaws were found in the udf_load_logicalvol() function in the Universal Disk Format (UDF) file system implementation in the Linux kernel. An attacker with physical access to a system could use these flaws to cause a denial of service or escalate their privileges. (CVE-2012-3400, Low)

* A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space.
(CVE-2012-3430, Low)

Red Hat would like to thank Pablo Neira Ayuso for reporting CVE-2012-3520; Theodore Ts'o for reporting CVE-2012-4508; Shachar Raindel for reporting CVE-2012-2133; and Kees Cook for reporting CVE-2012-0957. Upstream acknowledges Dmitry Monakhov as the original reporter of CVE-2012-4508. The CVE-2012-4565 issue was discovered by Rodrigo Freire of Red Hat, and the CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team.

This update also fixes multiple bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.

Users should upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.2.33-rt50, and correct these issues. The system must be rebooted for this update to take effect.

This update fixes the following security issues :

  - A use-after-free flaw was found in the madvise() system     call implementation in the Linux kernel. A local,     unprivileged user could use this flaw to cause a denial     of service or, potentially, escalate their privileges.
    (CVE-2012-3511, Moderate)

  - A flaw was found in the way the Linux kernel's TCP/IP     protocol suite implementation handled IPv6 sockets that     used the UDP_CORK option. A local, unprivileged user     could use this flaw to cause a denial of service.
    (CVE-2013-4162, Moderate)

  - An information leak flaw in the Linux kernel could allow     a local, unprivileged user to leak kernel memory to     user-space. (CVE-2013-2141, Low)

This update also fixes the following bugs :

  - A bug in the be2net driver prevented communication     between NICs using be2net. This update applies a patch     addressing this problem along with several other     upstream patches that fix various other problems.
    Traffic between NICs using the be2net driver now     proceeds as expected.

  - A recent patch fixing a problem that prevented     communication between NICs using the be2net driver     caused the firmware of NICs to become unresponsive, and     thus triggered a kernel panic. The problem was caused by     unnecessary usage of a hardware workaround that allows     skipping VLAN tag insertion. A patch has been applied     and the workaround is now used only when the     multi-channel configuration is enabled on the NIC. Note     that the bug only affected the NICs with firmware     version 4.2.xxxx.

  - A bug in the autofs4 mount expiration code could cause     the autofs4 module to falsely report a busy tree of NFS     mounts as 'not in use'. Consequently, automount     attempted to unmount the tree and failed with a 'failed     to umount offset' error, leaving the mount tree to     appear as empty directories. A patch has been applied to     remove an incorrectly used autofs dentry mount check and     the aforementioned problem no longer occurs.

  - A race condition in the be_open function in the be2net     driver could trigger the BUG_ON() macro, which resulted     in a kernel panic. A patch addressing this problem has     been applied and the race condition is now avoided by     enabling polling before enabling interrupts globally.
    The kernel no longer panics in this situation.

The system must be rebooted for this update to take effect.

It was found that when running a 32-bit binary that uses a large number of shared libraries, one of the libraries would always be loaded at a predictable address in memory. An attacker could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2012-1568 , Low)

(CVE-2012-3400 , Low)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-2044 advisory.

  - Use-after-free vulnerability in the Linux kernel before 3.3.6, when huge pages are enabled, allows local     users to cause a denial of service (system crash) or possibly gain privileges by interacting with a     hugetlbfs filesystem, as demonstrated by a umount operation that triggers improper handling of quota data.
    (CVE-2012-2133)

  - Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel     before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have     unspecified other impact via a crafted UDF filesystem. (CVE-2012-3400)

  - Multiple race conditions in the madvise_remove function in mm/madvise.c in the Linux kernel before 3.4.5     allow local users to cause a denial of service (use-after-free and system crash) via vectors involving a     (1) munmap or (2) close system call. (CVE-2012-3511)
