Linux

Linux kernel 2.6.x, when using both NFS and EXT3, allows remote attackers to cause a denial of service (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), which triggers an error and causes an exported directory to be remounted read-only.Show less

The ftdi_sio driver (usb/serial/ftdi_sio.c) in Linux kernel 2.6.x up to 2.6.17, and possibly later versions, allows local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued.Show less

The suid_dumpable support in Linux kernel 2.6.13 up to versions before 2.6.17.4, and 2.6.16 before 2.6.16.24, allows a local user to cause a denial of service (disk consumption) and possibly gain privileges via the PR_SET_DUMPABLE argument of the prctl function and a program that causes a core dump file to be created in a directory for which the user does not have permissions.Show less

The dvd_read_bca function in the DVD handling code in drivers/cdrom/cdrom.c in Linux kernel 2.2.16, and later versions, assigns the wrong value to a length variable, which allows local users to execute arbitrary code via a crafted USB Storage device that triggers a buffer overflow.Show less

SCTP conntrack (ip_conntrack_proto_sctp.c) in netfilter for Linux kernel 2.6.17 before 2.6.17.3 and 2.6.16 before 2.6.16.23 allows remote attackers to cause a denial of service (crash) via a packet without any chunks, which causes a variable to contain an invalid value that is later used to dereference a pointer.Show less

Linux kernel before 2.6.16.21 and 2.6.17, when running on PowerPC, does not perform certain required access_ok checks, which allows local users to read arbitrary kernel memory on 64-bit systems (signal_64.c) and cause a denial of service (crash) and possibly read kernel memory on 32-bit systems (signal_32.c).Show less

Race condition in Linux kernel 2.6.15 to 2.6.17, when running on SMP platforms, allows local users to cause a denial of service (crash) by creating and exiting a large number of tasks, then accessing the /proc entry of a task that is exiting, which causes memory corruption that leads to a failure in the prune_dcache function or a BUG_ON error in include/linux/list.h.Show less

The snmp_trap_decode function in the SNMP NAT helper for Linux kernel before 2.6.16.18 allows remote attackers to cause a denial of service (crash) via unspecified remote attack vectors that cause failures in snmp_trap_decode that trigger (1) frees of random memory or (2) frees of previously-freed memory (double-free) by snmp_trap_decode as well as its calling function, as demonstrated via certain test cases of the PROTOS SNMP test suite.Show less

SCTP in Linux kernel before 2.6.16.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a chunk length that is inconsistent with the actual length of provided parameters.Show less

Certain modifications to the Linux kernel 2.6.16 and earlier do not add the appropriate Linux Security Modules (LSM) file_permission hooks to the (1) readv and (2) writev functions, which might allow attackers to bypass intended access restrictions.Show less

Race condition in the do_add_counters function in netfilter for Linux kernel 2.6.16 allows local users with CAP_NET_ADMIN capabilities to read kernel memory by triggering the race condition in a way that produces a size value that is inconsistent with allocated memory, which leads to a buffer over-read in IPT_ENTRY_ITERATE.Show less

choose_new_parent in Linux kernel before 2.6.11.12 includes certain debugging code, which allows local users to cause a denial of service (panic) by causing certain circumstances involving termination of a parent process.Show less

lease_init in fs/locks.c in Linux kernel before 2.6.16.16 allows attackers to cause a denial of service (fcntl_setlease lockup) via actions that cause lease_init to free a lock that might not have been allocated on the stack.Show less
