Title: [CAID 35330, 35331]: CA Anti-Virus, CA Threat Manager, and

CA Anti-Spyware Console Login and File Mapping Vulnerabilities

CA Vuln ID (CAID): 35330, 35331

CA Advisory Date: 2007-05-09

Reported By: ZDI, iDefense

Impact: Attackers can cause a denial of service or potentially

execute arbitrary code.

Summary: CA Anti-Virus for the Enterprise, CA Threat Manager, and

CA Anti-Spyware contain multiple vulnerabilities that can allow an

attacker to cause a denial of service or possibly execute

arbitrary code. CA has issued patches to address the

vulnerabilities.

The first vulnerability, CVE-2007-2522, is due to insufficient

bounds checking on Console Server login credentials. A remote

attacker can use carefully constructed authentication credentials

to cause a stack based buffer overflow, which can potentially

result in arbitrary code execution.

The second vulnerability, CVE-2007-2523, is due to insufficient

bounds checking in InoCore.dll. A local attacker can modify the

contents of a file mapping to cause a stack based buffer overflow,

which can potentially result in arbitrary code execution. This

issue only affects CA Anti-Virus for the Enterprise and CA Threat

Manager.

Mitigating Factors: For CVE-2007-2522, the vulnerability applies

only to an installation on the x86 platform with the Console

Server installed.

Severity: CA has given these vulnerabilities a combined High risk

rating.

Affected Products:

CA Anti-Virus for the Enterprise (formerly eTrust Antivirus) r8

CA Threat Manager (formerly eTrust Integrated Threat Management) r8

CA Anti-Spyware for the Enterprise (formerly eTrust PestPatrol) r8

CA Protection Suites r3

Affected Platforms:

Windows

Status and Recommendation:

CA has issued an update to address the vulnerabilities. The

patched files are available as part of the product's automatic

content update. The following components must be enabled in order

to receive these updates: eTrust ITM Console Server must be

enabled to receive InoWeb.exe updates, and eTrust ITM Common must

be enabled to receive InoCore.dll updates.

How to determine if the installation is affected:

1. Using Windows Explorer, locate the files "InoWeb.exe" and

"InoCore.dll". By default, the files are located in the

"C:\Program Files\CA\eTrustITM" directory.

2. Right click on each of the files and select Properties.

3. Select the Version tab (or the Details tab if you are using

Windows Vista).

4. If either file version is earlier than indicated below, the

installation is vulnerable.

File Name File Version

InoWeb.exe 8.0.448.0

InoTask.dll 8.0.448.0

Workaround:

In situations where updating the product is not immediately

feasible, the following workaround can be used as a temporary

measure to reduce exposure.

For CVE-2007-2522, filter access to TCP port 12168.
