kernel: untangle the do_mremap()

The Linux kernel before 2.6.32.4 allows local users to gain privileges or cause a denial of service (panic) by calling the (1) mmap or (2) mremap function, aka the "do_mremap() mess" or "mremap/mmap mess."

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: bug in GFS/GFS2 locking code leads to dos

The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, 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 a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions.

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: local DoS via futex_lock_pi

The futex_lock_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly manage a certain reference count, which allows local users to cause a denial of service (OOPS) via vectors involving an unmount of an ext3 filesystem.

Unspecified vulnerability in Cisco Security Agent 5.2 before 5.2.0.285, when running on Linux, allows remote attackers to cause a denial of service (kernel panic) via "a series of TCP packets."

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: 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.

The cook codec in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.5, Mac RealPlayer 11.0 through 12.0.0.1444, and Linux RealPlayer 11.0.2.1744 does not properly perform initialization, which has unspecified impact and attack vectors.

kernel: sctp remote denial of service

The sctp_rcv_ootb function in the SCTP implementation in the Linux kernel before 2.6.23 allows remote attackers to cause a denial of service (infinite loop) via (1) an Out Of The Blue (OOTB) chunk or (2) a chunk of zero length.

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.

kernel: keyrings: find_keyring_by_name() can gain the freed keyring

Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel 2.6.34-rc5 and earlier allows local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.

arch/powerpc/mm/fsl_booke_mmu.c in KGDB in the Linux kernel 2.6.30 and other versions before 2.6.33, when running on PowerPC, does not properly perform a security check for access to a kernel page, which allows local users to overwrite arbitrary kernel memory, related to Fsl booke.

The TSB I-TLB load implementation in arch/sparc/kernel/tsb.S in the Linux kernel before 2.6.33 on the SPARC platform does not properly obtain the value of a certain _PAGE_EXEC_4U bit and consequently does not properly implement a non-executable stack, which makes it easier for context-dependent attackers to exploit stack-based buffer overflows via a crafted application.

The proc_oom_score function in fs/proc/base.c in the Linux kernel before 2.6.34-rc4 uses inappropriate data structures during selection of a candidate for the OOM killer, which might allow local users to cause a denial of service via unspecified patterns of task creation.

Unspecified vulnerability in HP Systems Insight Manager (SIM) 5.3, 5.3 Update 1, and 6.0 allows remote attackers to obtain sensitive information and modify data via unknown vectors.

The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel 2.6.29 through 2.6.32, and possibly other versions, does not ensure that a cloned file descriptor has been opened for reading, which allows local users to read sensitive information from a write-only file descriptor.

kernel: GFS2: The setflags ioctl() doesn't check file ownership

The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel before 2.6.34-git10 does not verify the ownership of a file, which allows local users to bypass intended access restrictions via a SETFLAGS ioctl request.
