Stack-based buffer overflow in Adobe Reader and Adobe Acrobat allows remote attackers to execute arbitrary code.
Apply updates per vendor instructions.
Risk Analysis
Adobe Reader and Adobe Acrobat contain a stack-based buffer overflow vulnerability, allowing remote attackers to execute arbitrary code. This flaw poses a critical security risk due to the potential for complete system compromise. Its high EPSS score of 0.93435 and inclusion in CISA's KEV indicate a high likelihood of exploitation.
This vulnerability is actively exploited in the wild. The nature of buffer overflows often allows for remote code execution, typically through specially crafted documents.
Administrators should ensure Adobe Reader and Adobe Acrobat are updated to the latest secure versions. Users should also exercise caution when opening PDF documents from untrusted sources.
Technical Analysis
CVE-2009-0927 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2009-0927 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
