kernel: infoleak if print-fatal-signals=1

The print_fatal_signal function in kernel/signal.c in the Linux kernel before 2.6.32.4 on the i386 platform, when print-fatal-signals is enabled, allows local users to discover the contents of arbitrary memory locations by jumping to an address and then reading a log file, and might allow local users to cause a denial of service (system slowdown or crash) by jumping to an address.

kvm: emulator privilege escalation

The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code, which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, a related issue to CVE-2010-0306.

kernel: x86: exceptions are not cleared in AMD FXSAVE workaround

The restore_fpu_checking function in arch/x86/include/asm/fpu-internal.h in the Linux kernel before 3.12.8 on the AMD K7 and K8 platforms does not clear pending exceptions before proceeding to an EMMS instruction, which allows local users to cause a denial of service (task kill) or possibly gain privileges via a crafted application.

Kernel: farsync: information leak in ioctl

The fst_get_iface function in drivers/net/wan/farsync.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCWANDEV ioctl call.

kernel: futex: Handle user space corruption gracefully

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.

Kernel: wanxl: information leak in ioctl

The wanxl_ioctl function in drivers/net/wan/wanxl.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an ioctl call.

Kernel: hamradio/yam: information leak in ioctl

The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call.

fwbuilder: Insecure temporary file handling in the generated iptables script

Firewall Builder 3.0.4, 3.0.5, and 3.0.6, when running on Linux, allows local users to gain privileges via a symlink attack on an unspecified temporary file that is created by the iptables script.

flash-plugin: security protection bypass (APSB14-02)

Adobe Flash Player before 11.7.700.260 and 11.8.x and 11.9.x before 12.0.0.38 on Windows and Mac OS X and before 11.2.202.335 on Linux, Adobe AIR before 4.0.0.1390, Adobe AIR SDK before 4.0.0.1390, and Adobe AIR SDK & Compiler before 4.0.0.1390 allow attackers to bypass unspecified protection mechanisms via unknown vectors.

flash-plugin: memory address layout randomization defeat (APSB14-02)

Adobe Flash Player before 11.7.700.260 and 11.8.x and 11.9.x before 12.0.0.38 on Windows and Mac OS X and before 11.2.202.335 on Linux, Adobe AIR before 4.0.0.1390, Adobe AIR SDK before 4.0.0.1390, and Adobe AIR SDK & Compiler before 4.0.0.1390 allow attackers to defeat the ASLR protection mechanism by leveraging an "address leak."

kernel: ipv6: fix ip6_dst_lookup_tail() NULL pointer dereference

The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

flash-plugin: multiple flaws lead to arbitrary code execution (APSB14-07)

Stack-based buffer overflow in Adobe Flash Player before 11.7.700.269 and 11.8.x through 12.0.x before 12.0.0.70 on Windows and Mac OS X and before 11.2.202.341 on Linux, Adobe AIR before 4.0.0.1628 on Android, Adobe AIR SDK before 4.0.0.1628, and Adobe AIR SDK & Compiler before 4.0.0.1628 allows attackers to execute arbitrary code via unspecified vectors.

flash-plugin: multiple flaws lead to arbitrary code execution (APSB14-07)

Adobe Flash Player before 11.7.700.269 and 11.8.x through 12.0.x before 12.0.0.70 on Windows and Mac OS X and before 11.2.202.341 on Linux, Adobe AIR before 4.0.0.1628 on Android, Adobe AIR SDK before 4.0.0.1628, and Adobe AIR SDK & Compiler before 4.0.0.1628 do not prevent access to address information, which makes it easier for attackers to bypass the ASLR protection mechanism via unspecified vectors.

kernel: sys_move_pages infoleak

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's node set.

kernel: emergency route cache flushing leads to node deadlock

A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic.

The nfs_lock function in fs/nfs/file.c in the Linux kernel 2.6.9 does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on an NFS filesystem and then changing this file's permissions, a related issue to CVE-2010-0727.

kernel: tipc: Fix oops on send prior to entering networked mode

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.

kernel: ipv6: skb is unexpectedly freed

Use-after-free vulnerability in net/ipv4/tcp_input.c in the Linux kernel 2.6 before 2.6.20, when IPV6_RECVPKTINFO is set on a listening socket, allows remote attackers to cause a denial of service (kernel panic) via a SYN packet while the socket is in a listening (TCP_LISTEN) state, which is not properly handled and causes the skb structure to be freed.

Director Agent 6.1 before 6.1.2.3 in IBM Systems Director on AIX and Linux uses incorrect permissions for the (1) diruninstall and (2) opt/ibm/director/bin/wcitinst scripts, which allows local users to gain privileges by executing these scripts.

kernel: gfs2 buffer overflow

gfs2 in the Linux kernel 2.6.18, and possibly other versions, does not properly handle when the gfs2_quota struct occupies two separate pages, which allows local users to cause a denial of service (kernel panic) via certain manipulations that cause an out-of-bounds write, as demonstrated by writing from an ext3 file system to a gfs2 file system.
