CVE-2011-0335 in Shockwave Player
Summary
by MITRE
Dirapi.dll in Adobe Shockwave Player before 11.6.0.626 allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2011-0317, CVE-2011-0318, CVE-2011-0319, CVE-2011-0320, CVE-2011-2119, and CVE-2011-2122.

Adobe Shockwave Player contains a critical memory corruption vulnerability in the dirapi.dll component that enables remote code execution or denial of service attacks. This vulnerability affects versions prior to 11.6.0.626 and represents a distinct threat vector from several other related vulnerabilities including CVE-2011-0317 through CVE-2011-2122. The flaw manifests through unspecified attack vectors within the Shockwave Player's handling of certain data structures, creating opportunities for malicious actors to manipulate memory contents and potentially execute arbitrary code on affected systems. The vulnerability falls under the broader category of memory corruption issues that are commonly classified as CWE-125 (Out-of-bounds Read) or CWE-787 (Out-of-bounds Write) depending on the specific exploitation technique. From an operational perspective, this vulnerability poses significant risk to users who may encounter malicious Shockwave content through web browsers or other applications that invoke the Shockwave Player component. Attackers can leverage this weakness to inject malicious code into the player's memory space, potentially gaining full system control or causing application crashes that result in denial of service conditions. The attack surface is particularly concerning given Shockwave Player's widespread deployment across enterprise and consumer environments, making it a prime target for exploit development. Organizations should prioritize immediate patching to version 11.6.0.626 or later, as this represents the first fixed release addressing the memory corruption issue. Security teams should also implement network-based mitigations such as content filtering and application whitelisting to prevent execution of untrusted Shockwave content. The vulnerability aligns with ATT&CK technique T1059.007 (Command and Scripting Interpreter: PowerShell) and T1203 (Exploitation for Client Execution) when exploited in targeted attacks, though the specific exploitation methods require careful analysis of the memory corruption patterns within dirapi.dll. Given the nature of memory corruption vulnerabilities, attackers typically employ techniques such as buffer overflows or use-after-free conditions to achieve their objectives, making this a particularly dangerous threat vector in the context of browser-based attacks and enterprise security environments. The vulnerability demonstrates how legacy multimedia players can become persistent attack vectors when not properly maintained and patched against known memory corruption flaws.
