PARTIAL Summary
The _CFNetConnectionWillEnqueueRequests function in CFNetwork 129.19 on Apple Mac OS X 10.4 through 10.4.10 allows remote attackers to cause a denial of service (application crash) via a crafted HTTP 301 response, which results in a NULL pointer dereference.

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.
- 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.

| description | BUGTRAQ ID: 22249 CVE(CAN) ID: CVE-2007-0464 Apple Mac OS X是苹果家族机器所使用的操作系统。 Mac OS X的CFNetwork处理畸形回应数据时存在漏洞，远程攻击者可能利用此漏洞导致客户端崩溃。 CFNetwork是一个Core Services框架，可提供解压网络协议所需的函数库。Mac OS X的CFNetwork没有正确地处理某些HTTP响应，_CFNetConnectionWillEnqueueRequests()函数可能会引用空指针。如果服务器向使用这个API的客户端发送了特制响应的话，就可以触发这个漏洞，导致拒绝服务的情况。 Apple Mac OS X 10.4 - 10.4.10 Apple MacOS X Server 10.4 - 10.4.10 临时解决方法： * 过滤通过CFNetwork API接收到的HTTP响应。 厂商补丁： Apple ----- 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://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=16036&cat=1&platform=osx&method=sa/MacOSXUpdCombo10.4.11Intel.dmg" target="_blank">http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=16036&cat=1&platform=osx&method=sa/MacOSXUpdCombo10.4.11Intel.dmg</a> <a href="http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=16051&cat=1&platform=osx&method=sa/MacOSXUpdCombo10.4.11PPC.dmg" target="_blank">http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=16051&cat=1&platform=osx&method=sa/MacOSXUpdCombo10.4.11PPC.dmg</a> |
