DSA-1787 linux-2.6.24 -- denial of service/privilege escalation/information leak

ID: oval:org.mitre.oval:def:8117Date: (C)2009-12-15   (M)2017-10-04
Class: PATCHFamily: unix




Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: Bryn M. Reeves reported a denial of service in the NFS filesystem. Local users can trigger a kernel BUG() due to a race condition in the do_setlk function. Hugo Dias reported a DoS condition in the ATM subsystem that can be triggered by a local user by calling the svc_listen function twice on the same socket and reading /proc/net/atm/*vc. Helge Deller discovered a denial of service condition that allows local users on PA-RISC systems to crash a system by attempting to unwind a stack contiaining userspace addresses. Alan Cox discovered a lack of minimum timeouts on SG_IO requests, which allows local users of systems using ATA to cause a denial of service by forcing drives into PIO mode. Vlad Malov reported an issue on 64-bit MIPS systems where a local user could cause a system crash by crafing a malicious binary which makes o32 syscalls with a number less than 4000. Zvonimir Rakamaric reported an off-by-one error in the ib700wdt watchdog driver which allows local users to cause a buffer underflow by making a specially crafted WDIOC_SETTIMEOUT ioctl call. Chris Evans discovered a situation in which a child process can send an arbitrary signal to its parent. Christian Borntraeger discovered an issue effecting the alpha, mips, powerpc, s390 and sparc64 architectures that allows local users to cause a denial of service or potentially gain elevated privileges. Vegard Nossum discovered a memory leak in the keyctl subsystem that allows local users to cause a denial of service by consuming all of kernel memory. Wei Yongjun discovered a memory overflow in the SCTP implementation that can be triggered by remote users, permitting remote code execution. Duane Griffin provided a fix for an issue in the eCryptfs subsystem which allows local users to cause a denial of service (fault or memory corruption). Pavel Roskin provided a fix for an issue in the dell_rbu driver that allows a local user to cause a denial of service (oops) by reading 0 bytes from a sysfs entry. Roel Kluin discovered inverted logic in the skfddi driver that permits local, unprivileged users to reset the driver statistics. Clement LECIGNE discovered a bug in the sock_getsockopt function that may result in leaking sensitive kernel memory. Peter Kerwien discovered an issue in the ext4 filesystem that allows local users to cause a denial of service (kernel oops) during a resize operation. Roland McGrath discovered an issue on amd64 kernels that allows local users to circumvent system call audit configurations which filter based on the syscall numbers or argument details. Jiri Olsa discovered that a local user can cause a denial of service (system hang) using a SHM_INFO shmctl call on kernels compiled with CONFIG_SHMEM disabled. This issue does not affect prebuilt Debian kernels. Mikulas Patocka reported an issue in the console subsystem that allows a local user to cause memory corruption by selecting a small number of 3-byte UTF-8 characters. Shaohua Li reported an issue in the AGP subsystem that may allow local users to read sensitive kernel memory due to a leak of uninitialized memory. Benjamin Gilbert reported a local denial of service vulnerability in the KVM VMX implementation that allows local users to trigger an oops. Thomas Pollet reported an overflow in the af_rose implementation that allows remote attackers to retrieve uninitialized kernel memory that may contain sensitive data. Oleg Nesterov discovered an issue in the exit_notify function that allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application. Daniel Hokka Zakrisson discovered that a kill(-1) is permitted to reach processes outside of the current process namespace. Pavan Naregundi reported an issue in the CIFS filesystem code that allows remote users to overwrite memory via a long nativeFileSystem field in a Tree Connect response during mount.
