CVE-2008-7013
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedNetService.dll in Baidu Hi IM allows remote servers to cause a denial of service (client crash) via a crafted login response that triggers a divide-by-zero error.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · low confidenceNetService.dll in Baidu Hi IM contains a divide-by-zero vulnerability triggered when the client receives a crafted login response from a remote server. This causes the client application to crash, resulting in a denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if NetService.dll exists on the systemSearch for NetService.dll in common Baidu Hi installation directories such as C:\Program Files\Baidu\Hi or C:\Program Files (x86)\Baidu\Hi, or use the search function to find the file anywhere on the system.Affected if NetService.dll is found on the system, indicating Baidu Hi IM is installed.
-
Verify Baidu Hi IM client is installedLook for the Baidu Hi IM executable (Hi.exe or similar) in typical installation paths like C:\Program Files\Baidu\Hi\ or check the Add or Remove Programs list in Windows Control Panel.Affected if Baidu Hi IM client software is installed on the system.
-
Confirm the vulnerable NetService.dll componentRight-click on NetService.dll, select Properties, and examine the File Version or Product Version information in the Details tab.Affected if NetService.dll version information is present, confirming the vulnerable component is in use.
-
Determine if network connectivity to untrusted servers is possibleReview network configuration and firewall rules to determine whether the Baidu Hi client could potentially connect to servers other than official Baidu servers, or check proxy/DNS settings that might allow redirection to malicious servers.Affected if The client can connect to network endpoints other than trusted Baidu servers, enabling an attacker to trigger the divide-by-zero condition.
If Baidu Hi IM with NetService.dll is installed and the client can connect to untrusted or compromised servers, the environment is affected by this vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince this is a client-side vulnerability triggered by malicious servers, users should only connect to trusted Baidu servers. The vendor would need to release a patch to add validation in the login response handling code to prevent the divide-by-zero condition.
