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 | CVE ID: CVE-2009-2970 UiPlayer网络视频播放软件是联合网视（UITV）公司的视频播放软件。 UiPlayer的安装目录下的UiCheck.dll是一个ActiveX控件，该控件允许在IE中加载。UiCheck.dll提供了一个接口函数 GetUiDllVersion()，该函数会把接收到的文件名参数拷贝到一个固定大小的缓冲区，如果文件名超长，就会导致栈溢出。 因为和百度等公司的合作，很多视频播放软件中也集成了UiPlayer，例如百度下吧等。 UiTV UiPlayer UiCheck.dll 1.0.0.6 Baidu BaiduV 临时解决方法： * 用regsvr32 /u UiCheck.dll命令反注册UiCheck.dll。 厂商补丁： Baidu ----- 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： http://v.baidu.com/xiaba/index.html UiTV ---- 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： http://www.uitv.cn/support/index.html |
