Adobe Reader and Acrobat Multiple Unspecified Vulnerabilities Security Advisory (CVE-2008-0655)
Executive & SecOps Summary
SECOPS ASSESSMENTAdobe Reader and Acrobat versions prior to 8.1.2 across all platforms
Remote attackers can execute arbitrary code or cause information disclosure by tricking users into opening a specially crafted PDF document
Immediately upgrade to Adobe Reader/Acrobat version 8.1.2 or later, or transition to the latest supported Acrobat Reader DC
Affected Products & Version Scope
Remediation & Live Workaround Commands
PATCH & WORKAROUND1. Official Patch & Version Upgrade Commands
The primary remediation is to upgrade to a secure, supported version of Adobe Acrobat Reader. In enterprise Windows environments, administrators can query installed versions using the following PowerShell command:
# Query installed Adobe Reader/Acrobat versions via registry
Get-WmiObject -Class Win32_Product |
Where-Object { $_.Name -like '*Adobe Acrobat*' -or $_.Name -like '*Adobe Reader*' } |
Select-Object Name, Version2. Temporary Workaround & Hardening Configuration
If immediate patching is not feasible, disable Acrobat JavaScript to mitigate the primary attack vector. This can be enforced via the Windows Registry:
Windows Registry Editor Version 5.00
; Disable JavaScript in Adobe Reader to mitigate exploitation vectors
[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\8.0\JSPrefs]
"bEnableJS"=dword:000000003. Log Audit & IoC Verification Commands
Use the following shell script to audit Linux endpoints for legacy, vulnerable Adobe Reader installations:
#!/bin/bash
# Search for legacy Adobe Reader installations and print version details
find /opt /usr/bin /usr/local -name 'acroread' -type f 2>/dev/null | while read -r bin; do
echo '[!] Found Adobe Reader binary at:' "$bin"
"$bin" -version 2>&1

Technical Root Cause & Exploitation Mechanics
1. Vulnerability Overview & Root Cause
CVE-2008-0655 represents multiple unspecified vulnerabilities within Adobe Reader and Acrobat versions prior to 8.1.2. The root cause lies in the improper handling and parsing of specific objects or embedded scripts within PDF files. This lack of robust input validation and memory management allows malformed PDF structures to corrupt the application's memory space.
2. Exploitation Mechanics & Attack Scenario
An attacker exploits this vulnerability by constructing a malicious PDF file containing a specific exploit payload. This file is typically distributed via phishing emails or hosted on compromised websites. When an unsuspecting user opens the document using an unpatched version of Adobe Reader, the parsing engine triggers a memory corruption or buffer overflow, leading to arbitrary code execution under the security context of the logged-in user.
3. Infrastructure & Business Impact
As this vulnerability is listed in the CISA KEV catalog, it has been actively exploited in the wild. Successful exploitation grants the attacker initial access to the endpoint, which can lead to lateral movement within the corporate network, sensitive data exfiltration, and full system compromise, posing a severe threat to organizational security.
Official Vendor Advisories & References
Multiple unspecified vulnerabilities in Adobe Reader and Acrobat before 8.1.2 have unknown impact and attack vectors.
