Oracle Linux 6 : kernel (ELSA-2011-0421)

high Nessus Plugin ID 68247

Synopsis

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

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-0421 advisory.

- The cxgb_extension_ioctl function in drivers/net/cxgb3/cxgb3_main.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a CHELSIO_GET_QSET_NUM ioctl call. (CVE-2010-3296)

- 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-2010-4346)

- 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-2010-4526)

- The orinoco_ioctl_set_auth function in drivers/net/wireless/orinoco/wext.c in the Linux kernel before 2.6.37 does not properly implement a TKIP protection mechanism, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading Wi-Fi frames. (CVE-2010-4648)

- net/core/ethtool.c in the Linux kernel before 2.6.36 does not initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability for an ethtool ioctl call. (CVE-2010-4655)

- The iowarrior_write function in drivers/usb/misc/iowarrior.c in the Linux kernel before 2.6.37 does not properly allocate memory, which might allow local users to trigger a heap-based buffer overflow, and consequently cause a denial of service or gain privileges, via a long report. (CVE-2010-4656)

- The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel before 2.6.38-rc2 does not check the sign of a certain integer field, which allows local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value. (CVE-2011-0521)

- Race condition in the cm_work_handler function in the InfiniBand driver (drivers/infiniband/core/cma.c) in Linux kernel 2.6.x allows remote attackers to cause a denial of service (panic) by sending an InfiniBand request while other request handlers are still running, which triggers an invalid pointer dereference.
(CVE-2011-0695)

- The task_show_regs function in arch/s390/kernel/traps.c in the Linux kernel before 2.6.38-rc4-next-20110216 on the s390 platform allows local users to obtain the values of the registers of an arbitrary process by reading a status file under /proc/. (CVE-2011-0710)

- The br_multicast_add_group function in net/bridge/br_multicast.c in the Linux kernel before 2.6.38, when a certain Ethernet bridge configuration is used, allows local users to cause a denial of service (memory corruption and system crash) by sending IGMP packets to a local interface. (CVE-2011-0716)

- The napi_reuse_skb function in net/core/dev.c in the Generic Receive Offload (GRO) implementation in the Linux kernel before 2.6.38 does not reset the values of certain structure members, which might allow remote attackers to cause a denial of service (NULL pointer dereference) via a malformed VLAN frame.
(CVE-2011-1478)

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

Solution

Update the affected packages.
