Race condition in the findgetblockslow function in the ISO9660 filesystem in Linux 2.6.18 and possibly other versions allows local users to cause a denial of service (infinite loop) by mounting a crafted ISO9660 filesystem containing malformed data structures.
The copyfromuser function in the uaccess code in Linux kernel 2.6 before 2.6.19-rc1, when running on s390, does not properly clear a kernel buffer, which allows local user space programs to read portions of kernel memory by "appending to a file from a bad address," which triggers a fault that prevents the unused memory from being cleared in the kernel buffer.
The blockpreparewrite function in fs/buffer.c for Linux kernel 2.6.x before 2.6.13 does not properly clear buffers during certain error conditions, which allows local users to read portions of files that have been unlinked.
cryptoloop on Linux kernel 2.6.x, when used on certain file systems with a block size 1024 or greater, has certain "IV computation" weaknesses that allow watermarked files to be detected without decryption.
Unknown vulnerability in the system call filtering code in the audit subsystem for Red Hat Enterprise Linux 3 allows local users to cause a denial of service (system crash) via unknown vectors.
Integer overflow in the vcresize function in the Linux kernel 2.4 and 2.6 before 2.6.10 allows local users to cause a denial of service (kernel crash) via a short new screen value, which leads to a buffer overflow.
Integer overflow in the ipoptionsget function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (kernel crash) via a cmsglen that contains a -1, which leads to a buffer overflow.
Memory leak in the ipoptionsget function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ipcmsgsend function.
Race condition in Linux kernel 2.6 allows local users to read the environment variables of another process that is still spawning via /proc/.../cmdline.
Race condition in SELinux 2.6.x through 2.6.9 allows local users to cause a denial of service (kernel crash) via SOCKSEQPACKET unix domain sockets, which are not properly handled in the sockdgramsendmsg function.
The openexec function in the execve functionality (exec.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, allows local users to read non-readable ELF binaries by using the interpreter (PTINTERP) functionality.
The binfmt functionality in the Linux kernel, when "memory overcommit" is enabled, allows local users to cause a denial of service (kernel oops) via a malformed a.out binary.
The scmsend function in the scm layer for Linux kernel 2.4.x up to 2.4.28, and 2.6.x up to 2.6.9, allows local users to cause a denial of service (system hang) via crafted auxiliary messages that are passed to the sendmsg function, which causes a deadlock condition.
Buffer overflow in sysctl in the Linux Kernel 2.6 before 2.6.15 allows local users to corrupt user memory and possibly cause a denial of service via a long string, which causes sysctl to write a zero byte outside the buffer. NOTE: since the sysctl is called from a userland program that provides the argument, this might not be a vulnerability, unless a legitimate user-assisted or setuid scenario can be identified.
The securelevels implementation in NetBSD 2.1 and earlier, and Linux 2.6.15 and earlier, allows local users to bypass time setting restrictions and set the clock backwards by setting the clock ahead to the maximum unixtime value (19 Jan 2038), which then wraps around to the minimum value (13 Dec 1901), which can then be set ahead to the desired time, aka "settimeofday() time wrap."
The mqopen system call in Linux kernel 2.6.9, in certain situations, can decrement a counter twice ("double decrement") as a result of multiple calls to the mntput function when the dentryopen function call fails, which allows local users to cause a denial of service (panic) via unspecified attack vectors.
The NAT code (1) ipnatprototcp.c and (2) ipnatprotoudp.c in Linux kernel 2.6 before 2.6.13 and 2.4 before 2.4.32-rc1 incorrectly declares a variable to be static, which allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption.
The sysgetthreadarea function in process.c in Linux 2.6 before 2.6.12.4 and 2.6.13 does not clear a data structure before copying it to userspace, which might allow a user process to obtain sensitive information.
Linux kernel 2.6.8 to 2.6.14-rc2 allows local users to cause a denial of service (kernel OOPS) via a userspace process that issues a USB Request Block (URB) to a USB device and terminates before the URB is finished, which leads to a stale pointer reference.
Multiple vulnerabilities in Linux kernel before 2.6.13.2 allow local users to cause a denial of service (kernel OOPS from null dereference) via (1) fput in a 32-bit ioctl on 64-bit x86 systems or (2) sockfdput in the 32-bit routingioctl function on 64-bit systems.
The udpv6getport function in udp.c in Linux 2.6 before 2.6.14-rc5, when running IPv6, allows local users to cause a denial of service (infinite loop and crash).
The iptrecent kernel module (iptrecent.c) in Linux kernel 2.6.12 and earlier does not properly perform certain time tests when the jiffies value is greater than LONGMAX, which can cause iptrecent netfilter rules to block too early, a different vulnerability than CVE-2005-2872.
Memory leak in the seqfile implementation in the SCSI procfs interface (sg.c) in Linux kernel 2.6.13 and earlier allows local users to cause a denial of service (memory consumption) via certain repeated reads from the /proc/scsi/sg/devices file, which is not properly handled when the next() iterator returns NULL or an error.
The rawsendmsg function in the Linux kernel 2.6 before 2.6.13.1 allows local users to cause a denial of service (change hardware state) or read from arbitrary memory via crafted input.
The Linux kernel 2.6 before 2.6.12.1 allows local users to cause a denial of service (kernel panic) via a non group-leader thread executing a different program than was pending in itimer, which causes the signal to be delivered to the old group-leader task, which does not exist.
The (1) it87 and (2) via686a drivers in I2C for Linux 2.6.x before 2.6.11.8, and 2.6.12 before 2.6.12-rc2, create the sysfs "alarms" file with write permissions, which allows local users to cause a denial of service (CPU consumption) by attempting to write to the file, which does not have an associated store function.
The keyuserlookup function in security/keys/key.c in Linux kernel 2.6.10 to 2.6.11.8 may allow attackers to cause a denial of service (oops) via SMP.
Some futex functions in futex.c for Linux kernel 2.6.x perform getuser calls while holding the mmapsem semaphore, which could allow local users to cause a deadlock condition in dopagefault by triggering getuser faults while another thread is executing mmap or other functions.
Integer overflow in sysepollwait in eventpoll.c for Linux kernel 2.6 to 2.6.11 allows local users to overwrite kernel memory via a large number of events.
Multiple integer signedness errors in the sgscsiioctl function in scsiioctl.c for Linux 2.6.x allow local users to read or modify kernel memory via negative integers in arguments to the scsi ioctl, which bypass a maximum length check before calling the copyfromuser and copytouser functions.
