It includes one version update. Description: The openSUSE 11.4 kernel was updated to 2.6.37.6 fixing lots of bugs and security issues. Following security issues have been fixed: CVE-2011-1493: In the rose networking stack, when parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure. CVE-2011-1182: Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs. CVE-2011-1478: An issue in the core GRO code where an skb belonging to an unknown VLAN is reused could result in a NULL pointer dereference. CVE-2011-1476: Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables. CVE-2011-1477: Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation. CVE-2011-0191: A information leak in the XFS geometry calls could be used by local attackers to gain access to kernel information. CVE-2011-0711: A stack memory information leak in the xfs FSGEOMETRY_V1 ioctl was fixed. CVE-2011-0521: The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel did not check the sign of a certain integer field, which allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value. CVE-2011-1010: The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions. CVE-2011-0712: Multiple buffer overflows in the caiaq Native Instruments USB audio functionality in the Linux kernel might have allowed attackers to cause a denial of service or possibly have unspecified other impact via a long USB device name, related to (1) the snd_usb_caiaq_audio_init function in sound/usb/caiaq/audio.c and (2) the snd_usb_caiaq_midi_init function in sound/usb/caiaq/midi.c. CVE-2011-1013: A signedness issue in the drm ioctl handling could be used by local attackers to potentially overflow kernel buffers and execute code. CVE-2011-1082: The epoll subsystem in Linux did not prevent users from creating circular epoll file structures, potentially leading to a denial of service (kernel deadlock). CVE-2010-4650: A kernel buffer overflow in the cuse server module was fixed, which might have allowed local privilege escalation. However only CUSE servers could exploit it and /dev/cuse is normally restricted to root. CVE-2011-1093: A bug was fixed in the DCCP networking stack where the order of dccp_rcv_state_process() still permitted reception even after closing the socket. A Reset after close thus causes a NULL pointer dereference by not preventing operations on an already torn-down socket. CVE-2011-1163: The code for evaluating OSF partitions (in fs/partitions/osf.c) contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions. CVE-2011-1012: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained a bug that could crash the kernel for certain corrupted LDM partitions. CVE-2011-1581: Doing bridging with devices with more than 16 receive queues could crash the kernel. CVE-2011-1160: Kernel information via the TPM devices could by used by local attackers to read kernel memory. CVE-2011-1577: The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code. CVE-2011-1180: In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory. CVE-2011-1016: The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values. Special Instructions and Notes: Please reboot the system after installing this update. Patch Instructions: To install this openSUSE Security Update use YaST online_update.
