Summary
by MITRE
Adobe Reader and Acrobat 9.x before 9.5.3, 10.x before 10.1.5, and 11.x before 11.0.1 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2012-1530, CVE-2013-0601, CVE-2013-0616, CVE-2013-0619, CVE-2013-0620, and CVE-2013-0623.

Adobe Reader and Acrobat versions 9.x before 9.5.3, 10.x before 10.1.5, and 11.x before 11.0.1 contain a critical memory corruption vulnerability that enables remote code execution or denial of service attacks through unspecified attack vectors. This vulnerability represents a distinct threat model from several other CVEs published in the same timeframe, including CVE-2012-1530, CVE-2013-0601, CVE-2013-0616, CVE-2013-0619, CVE-2013-0620, and CVE-2013-0623, indicating that the flaw exists in different code paths within the software architecture. The vulnerability stems from improper memory handling during the processing of maliciously crafted PDF documents, where attackers can manipulate memory structures through carefully constructed input data that bypasses normal validation checks. This particular flaw aligns with CWE-125, which describes out-of-bounds read conditions, and CWE-787, which covers out-of-bounds write operations, both of which are common attack vectors in memory corruption vulnerabilities. The security implications extend to the ATT&CK framework's technique T1203, which encompasses exploitation of remote services through memory corruption, and T1059, which covers command and scripting interpreters that attackers may leverage after successful exploitation. The attack surface for this vulnerability encompasses any user who opens a malicious PDF file, making it particularly dangerous for enterprise environments where document sharing is common. Attackers can exploit this weakness by crafting PDF documents that trigger memory corruption when processed by the vulnerable Adobe applications, potentially leading to arbitrary code execution with the privileges of the user running the application.
The technical nature of this vulnerability involves memory corruption that can manifest in multiple ways including heap-based buffer overflows, stack-based buffer overflows, or use-after-free conditions during PDF parsing operations. When Adobe Reader or Acrobat processes malformed PDF content, the application fails to properly validate memory allocations and deallocations, creating opportunities for attackers to manipulate memory contents. The vulnerability's impact ranges from denial of service through application crashes to complete system compromise when attackers successfully execute malicious code within the application context. This type of vulnerability is particularly challenging to defend against because it often requires deep understanding of the PDF specification and the internal memory management of Adobe's implementation. The exploitation typically occurs when users open malicious documents, making social engineering attacks more effective since they can combine with the technical vulnerability to achieve successful compromises. Organizations may observe this vulnerability being exploited in the wild through spear-phishing campaigns where attackers send PDF files that contain embedded malicious code designed to exploit the memory corruption issue.
Organizations should prioritize immediate patching of affected Adobe Reader and Acrobat versions to mitigate the risk of exploitation. The recommended mitigation strategy includes implementing strict document validation policies, deploying sandboxing technologies to isolate PDF processing, and establishing network-based intrusion detection systems to monitor for exploitation attempts. Security teams should also consider implementing application whitelisting policies that restrict execution of unauthorized Adobe applications and regularly audit PDF handling processes within their environments. The vulnerability's classification as a memory corruption issue aligns with industry best practices for vulnerability management, particularly those outlined in the NIST Cybersecurity Framework and ISO 27001 standards for information security management. Organizations should also consider implementing user education programs to reduce the risk of social engineering attacks that could exploit this vulnerability, as user behavior remains a critical factor in successful exploitation. Additionally, network segmentation and email filtering solutions should be deployed to prevent delivery of malicious PDF files to end users, while endpoint protection solutions should be configured to monitor for suspicious PDF processing activities that could indicate exploitation attempts. The vulnerability's persistence across multiple versions of Adobe's software indicates a fundamental flaw in the memory management implementation that requires comprehensive remediation through official patches provided by Adobe.
