Summary

Buffer overflow in the regular expression handler in Red Hat Directory Server 8.0 and 7.1 before SP6 allows remote attackers to cause a denial of service (slapd crash) and possibly execute arbitrary code via a crafted LDAP query that triggers the overflow during translation to a regular expression.

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.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

descriptionBUGTRAQ ID: 29126 CVE(CAN) ID: CVE-2008-1677 Red Hat目录服务器是用于集中管理应用设置、组数据、策略等内容的基于LDAP的服务器。 Red Hat目录服务器使用固定大小的缓冲区储存LDAP搜索中所使用的正则表达式,在将用户提供的LDAP请求中的搜索模式翻译成正则表达式时可能会触发缓冲区溢出,导致slapd守护程序崩溃或执行任意代码。任何可以执行LDAP搜索的用户都可以触发这个溢出,如果ACL允许匿名访问(默认配置)的话也包括匿名用户。 RedHat Directory Server 8.0 RedHat Directory Server 7.1 RedHat ------ RedHat已经为此发布了一个安全公告(RHSA-2008:0268-01)以及相应补丁: RHSA-2008:0268-01:Critical: Red Hat Directory Server 7.1 Service Pack 6 security update 链接:<a href=https://www.redhat.com/support/errata/RHSA-2008-0268.html target=_blank>https://www.redhat.com/support/errata/RHSA-2008-0268.html</a>
