Linux: >> Linux Kernel >> 2.1.78 Security Vulnerabilities
fs/nfs/client.c in the Linux kernel before 2.6.23 does not properly initialize a certain structure member that stores the maximum NFS filename length, which allows local users to cause a denial of service (OOPS) via a long filename, related to the encode_lookup function.

The kill_something_info function in kernel/signal.c in the Linux kernel before 2.6.28 does not consider PID namespaces when processing signals directed to PID -1, which allows local users to bypass the intended namespace isolation, and send arbitrary signals to all processes in all namespaces, via a kill command.

The __inet6_check_established function in net/ipv6/inet6_hashtables.c in the Linux kernel before 2.6.29, when Network Namespace Support (aka NET_NS) is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via vectors involving IPv6 packets.

The cache manager in the client in OpenAFS 1.0 through 1.4.8 and 1.5.0 through 1.5.58, and IBM AFS 3.6 before Patch 19, on Linux allows remote attackers to cause a denial of service (system crash) via an RX response with a large error-code value that is interpreted as a pointer and dereferenced, related to use of the ERR_PTR macro.

The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel before 2.6.29.1 on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka "Long mode enable") bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform.

net/ipv4/udp.c in the Linux kernel before 2.6.29.1 performs an unlocking step in certain incorrect circumstances, which allows local users to cause a denial of service (panic) by reading zero bytes from the /proc/net/udp file and unspecified other files, related to the "udp seq_file infrastructure."

nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

The icmp_send function in net/ipv4/icmp.c in the Linux kernel before 2.6.25, when configured as a router with a REJECT route, does not properly manage the Protocol Independent Destination Cache (aka DST) in some situations involving transmission of an ICMP Host Unreachable message, which allows remote attackers to cause a denial of service (connectivity outage) by sending a large series of packets to many destination IP addresses within this REJECT route, related to an "rt_cache leak."

Sun xVM VirtualBox 2.0.0, 2.0.2, 2.0.4, 2.0.6r39760, 2.1.0, 2.1.2, and 2.1.4r42893 on Linux allows local users to gain privileges via a hardlink attack, which preserves setuid/setgid bits on Linux, related to DT_RPATH:$ORIGIN.

The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel before 2.6.28.5, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program.
