CVE-2010-4565

kernel: CAN info leak

The bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel 2.6.36 and earlier creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename.

CVE-2010-4526

kernel: sctp: a race between ICMP protocol unreachable and connect()

Race condition in the sctp_icmp_proto_unreachable function in net/sctp/input.c in Linux kernel 2.6.11-rc2 through 2.6.33 allows remote attackers to cause a denial of service (panic) via an ICMP unreachable message to a socket that is already locked by a user, which causes the socket to be freed and triggers list corruption, related to the sctp_wait_for_connect function.

CVE-2010-4347

kernel: local privilege escalation via /sys/kernel/debug/acpi/custom_method

The ACPI subsystem in the Linux kernel before 2.6.36.2 uses 0222 permissions for the debugfs custom_method file, which allows local users to gain privileges by placing a custom ACPI method in the ACPI interpreter tables, related to the acpi_debugfs_init function in drivers/acpi/debugfs.c.

CVE-2010-4346

kernel: install_special_mapping skips security_file_mmap check

The install_special_mapping function in mm/mmap.c in the Linux kernel before 2.6.37-rc6 does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application.

CVE-2009-4895

kernel: tty->pgrp races

Race condition in the tty_fasync function in drivers/char/tty_io.c in the Linux kernel before 2.6.32.6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via unknown vectors, related to the put_tty_queue and __f_setown functions. NOTE: the vulnerability was addressed in a different way in 2.6.32.9.

CVE-2008-7256

kernel: nfsd: fix vm overcommit crash

mm/shmem.c in the Linux kernel before 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1643.

kernel: mm: mem allocated invisible to oom_kill() when not attached to any threads

fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial of service (memory consumption) via a crafted exec system call, aka an "OOM dodging issue," a related issue to CVE-2010-3858.

kernel: missing tty ops write function presence check in hci_uart_tty_open()

The hci_uart_tty_open function in the HCI UART driver (drivers/bluetooth/hci_ldisc.c) in the Linux kernel 2.6.36, and possibly other versions, does not verify whether the tty has a write operation, which allows local users to cause a denial of service (NULL pointer dereference) via vectors related to the Bluetooth driver.

CVE-2010-4179

plugin: enable QUEUE_ALL_USERS_TRUSTED for Submit/Hold/Release/Remove ops

The installation documentation for Red Hat Enterprise Messaging, Realtime and Grid (MRG) 1.3 recommends that Condor should be configured so that the MRG Management Console (cumin) can submit jobs for users, which creates a trusted channel with insufficient access control that allows local users with the ability to publish to a broker to run jobs as arbitrary users via Condor QMF plug-ins.
