[原文]The ext2_make_empty function call in the Linux kernel before 2.6.11.6 does not properly initialize memory when creating a block for a new directory entry, which allows local users to obtain potentially sensitive information by reading the block.


[CNNVD]Linux Kernel ext2实现信息泄漏漏洞(CNNVD-200505-069)

        Linux Kernel是开发源码操作系统Linux的内核。
        Linux在实现ext2文件系统时所使用的ext2_make_empty()函数存在信息泄漏漏洞。在创建目录时,系统从kernel内存获取新的内存块存储初始的目录条目('.'和'..')。因为会未经初始化就使用这个内存块写入磁盘,因此可能导致泄漏内存块空间中的信息。 每次创建目录时最多可泄漏4072(4096-2*12)字节的Kernel内存。在向目录内存块中添加了额外的条目时,这个数量会降低。注意:由于ext2实现使用dir-in-pagecache设计,因此可能泄漏任何部分的kernel内存,不仅仅是旧的磁盘/文件系统数据。

Ubuntu Security Notice USN-103-1 - The LInux 2.6.8.1 kernel suffers from about a half dozen serious vulnerabilities.

===========================================================
Ubuntu Security Notice USN-103-1	     April 01, 2005
linux-source-2.6.8.1 vulnerabilities
CAN-2005-0400, CAN-2005-0749, CAN-2005-0750, CAN-2005-0815,
CAN-2005-0839
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

linux-image-2.6.8.1-5-386
linux-image-2.6.8.1-5-686
linux-image-2.6.8.1-5-686-smp
linux-image-2.6.8.1-5-amd64-generic
linux-image-2.6.8.1-5-amd64-k8
linux-image-2.6.8.1-5-amd64-k8-smp
linux-image-2.6.8.1-5-amd64-xeon
linux-image-2.6.8.1-5-k7
linux-image-2.6.8.1-5-k7-smp
linux-image-2.6.8.1-5-power3
linux-image-2.6.8.1-5-power3-smp
linux-image-2.6.8.1-5-power4
linux-image-2.6.8.1-5-power4-smp
linux-image-2.6.8.1-5-powerpc
linux-image-2.6.8.1-5-powerpc-smp
linux-patch-debian-2.6.8.1

The problem can be corrected by upgrading the affected package to
version 2.6.8.1-16.13. You need to reboot the computer after doing a
standard system upgrade to effect the necessary changes. 

Details follow:

Mathieu Lafon discovered an information leak in the ext2 file system
driver. When a new directory was created, the ext2 block written to
disk was not initialized, so that previous memory contents (which
could contain sensitive data like passwords) became visible on the raw
device. This is particularly important if the target device is
removable and thus can be read by users other than root.
(CAN-2005-0400)

Yichen Xie discovered a Denial of Service vulnerability in the ELF
loader. A specially crafted ELF library or executable could cause an
attempt to free an invalid pointer, which lead to a kernel crash.
(CAN-2005-0749)

Ilja van Sprundel discovered that the bluez_sock_create() function did
not check its "protocol" argument for negative values. A local
attacker could exploit this to execute arbitrary code with root
privileges by creating a Bluetooth socket with a specially crafted
protocol number. (CAN-2005-0750)

Michal Zalewski discovered that the iso9660 file system driver fails
to check ranges properly in several cases. Mounting a specially
crafted CD-ROM may have caused a buffer overflow leading to a kernel
crash or even arbitrary code execution. (CAN-2005-0815)

Previous kernels did not restrict the use of the N_MOUSE line
discipline in the serial driver. This allowed an unprivileged user to
inject mouse movement and/or keystrokes (using the sunkbd driver) into
the input subsystem, taking over the console or an X session, where
another user is logged in.  (CAN-2005-0839)

A Denial of Service vulnerability was found in the tmpfs driver, which
is commonly used to mount RAM disks below /dev/shm and /tmp. The
shm_nopage() did not properly verify its address argument, which could
be exploited by a local user to cause a kernel crash with invalid
addresses.

15115
Linux Kernel ext2 Directory Creation Arbitrary Memory Disclosure
Local Access Required Information Disclosure
Loss of Confidentiality
Exploit Unknown Vendor Verified

- 漏洞描述

The Linux kernel EXT2 filesystem contains a flaw that may lead to an unauthorized information disclosure. The problem is that the 'ext2_make_empty()' function does not properly clear filesystem contents when creating a directory and the block written to store the '.' and '..' directory entries remains uninitialized. Up to 4,072 bytes of kernel memory may be leaked on each directory creation, which may allow a malicious user to disclose sensitive kernel memory contents resulting in a loss of confidentiality.

- 解决方案

Upgrade to version 2.4.30-rc2, 2.6.11.6 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
