Summary

The copy_from_user_mmap_sem function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which allow local users to read from arbitrary kernel memory locations.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

descriptionBUGTRAQ ID: 27796 CVE(CAN) ID: CVE-2008-0010 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的实现上存在漏洞，本地攻击者可能利用此漏洞获取内核内存的敏感信息。 Linux Kernel的fs/splice.c文件中的copy_from_user_mmap_sem()函数未经验证用户提供的指针便使用__copy_from_user_inatomic()拷贝了用户进程内存中的数据： ---8&lt;--- fs/splice.c:1188 ---8&lt;--- partial = __copy_from_user_inatomic(dst, src, n); ---8&lt;--- fs/splice.c:1188 ---8&lt;--- 这可能允许本地攻击者通过特制的vmsplice()系统调用读取任意内核内存。 Linux kernel 2.6.22 - 2.6.24 厂商补丁： Debian ------ Debian已经为此发布了一个安全公告（DSA-1494-2）以及相应补丁: DSA-1494-2：New linux-2.6 packages fix privilege escalation 链接：<a href=http://www.debian.org/security/2008/dsa-1494 target=_blank>http://www.debian.org/security/2008/dsa-1494</a> 补丁安装方法： 1. 手工安装补丁包： 首先，使用下面的命令来下载补丁软件： # wget url (url是补丁下载链接地址) 然后，使用下面的命令来安装补丁： # dpkg -i file.deb (file是相应的补丁名) 2. 使用apt-get自动安装补丁包： 首先，使用下面的命令更新内部数据库： # apt-get update 然后，使用下面的命令安装更新软件包： # apt-get upgrade Linux ----- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： <a href=http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.24.1.bz2 target=_blank>http://www.kernel.org/pub/linux/kernel/v2.6/patch-2.6.24.1.bz2</a>
