Synopsis
The remote Mandriva Linux host is missing one or more security updates.Description
Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :fs/namei.c in Linux kernel 2.6.18 through 2.6.34 does not always follow NFS automount symlinks, which allows attackers to have an unknown impact, related to LOOKUP_FOLLOW. (CVE-2010-1088)
The tc_fill_tclass function in net/sched/sch_api.c in the tc subsystem in the Linux kernel 2.4.x before 2.4.37.6 and 2.6.x before 2.6.31-rc9 does not initialize certain (1) tcm__pad1 and (2) tcm__pad2 structure members, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. (CVE-2009-3228)
The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel node set. (CVE-2010-0415)
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. (CVE-2009-3620)
The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance (PI) futex, which allows local users to cause a denial of service (OOPS) and possibly have unspecified other impact via vectors involving modification of the futex value from user space. (CVE-2010-0622)
The kvm_arch_vcpu_ioctl_set_sregs function in the KVM in Linux kernel 2.6 before 2.6.30, when running on x86 systems, does not validate the page table root in a KVM_SET_SREGS call, which allows local users to cause a denial of service (crash or hang) via a crafted cr3 value, which triggers a NULL pointer dereference in the gfn_to_rmap function.
(CVE-2009-2287)
The handle_dr function in arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 2.6.31.1 does not properly verify the Current Privilege Level (CPL) before accessing a debug register, which allows guest OS users to cause a denial of service (trap) on the host OS via a crafted application. (CVE-2009-3722)
The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. (CVE-2009-4308)
The eisa_eeprom_read function in the parisc isa-eeprom component (drivers/parisc/eisa_eeprom.c) in the Linux kernel before 2.6.31-rc6 allows local users to access restricted memory via a negative ppos argument, which bypasses a check that assumes that ppos is positive and causes an out-of-bounds read in the readb function.
(CVE-2009-2846)
Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions.
(CVE-2010-2521)
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. (CVE-2008-7256)
The release_one_tty function in drivers/char/tty_io.c in the Linux kernel before 2.6.34-rc4 omits certain required calls to the put_pid function, which has unspecified impact and local attack vectors.
(CVE-2010-1162)
mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, 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. (CVE-2010-1643)
The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. (CVE-2010-1173)
The Transparent Inter-Process Communication (TIPC) functionality in Linux kernel 2.6.16-rc1 through 2.6.33, and possibly other versions, allows local users to cause a denial of service (kernel OOPS) by sending datagrams through AF_TIPC before entering network mode, which triggers a NULL pointer dereference. (CVE-2010-1187)
The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. (CVE-2010-1173)
fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel before 2.6.34-rc4 allows remote attackers to cause a denial of service (panic) via an SMB response packet with an invalid CountHigh value, as demonstrated by a response from an OS/2 server, related to the CIFSSMBWrite and CIFSSMBWrite2 functions. (CVE-2010-2248)
Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel before 2.6.35 might allow local users to gain privileges or cause a denial of service (system crash) via unspecified vectors.
(CVE-2010-2492)
The xfs_swapext function in fs/xfs/xfs_dfrag.c in the Linux kernel before 2.6.35 does not properly check the file descriptors passed to the SWAPEXT ioctl, which allows local users to leverage write access and obtain read access by swapping one file into another file.
(CVE-2010-2226)
The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c. (CVE-2010-2798)
The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server. (CVE-2010-2240)
The drm_ioctl function in drivers/gpu/drm/drm_drv.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.27.53, 2.6.32.x before 2.6.32.21, 2.6.34.x before 2.6.34.6, and 2.6.35.x before 2.6.35.4 allows local users to obtain potentially sensitive information from kernel memory by requesting a large memory-allocation amount. (CVE-2010-2803)
Integer overflow in net/can/bcm.c in the Controller Area Network (CAN) implementation in the Linux kernel before 2.6.27.53, 2.6.32.x before 2.6.32.21, 2.6.34.x before 2.6.34.6, and 2.6.35.x before 2.6.35.4 allows attackers to execute arbitrary code or cause a denial of service (system crash) via crafted CAN traffic. (CVE-2010-2959)
Double free vulnerability in the snd_seq_oss_open function in sound/core/seq/oss/seq_oss_init.c in the Linux kernel before 2.6.36-rc4 might allow local users to cause a denial of service or possibly have unspecified other impact via an unsuccessful attempt to open the /dev/sequencer device. (CVE-2010-3080)
A vulnerability in Linux kernel caused by insecure allocation of user space memory when translating system call inputs to 64-bit. A stack pointer underflow can occur when using the compat_alloc_user_space method with an arbitrary length input. (CVE-2010-3081)
The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression. (CVE-2010-3301)
