Summary

CVE-2009-3953 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Adobe Acrobat. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 0.3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is an array boundary issue, tracked as CWE-787, in the U3D implementation of Adobe Reader and Acrobat. It affects versions 9.x before 9.3, 8.x before 8.2 on Windows and Mac OS X, and 7.x before 7.1.4, and is distinct from CVE-2009-2994. Malformed U3D data supplied inside a PDF document can trigger the flaw.

An unauthenticated remote attacker can exploit the issue by delivering a crafted PDF to a target user. If the recipient opens the document in an affected reader, the attacker may achieve arbitrary code execution with the privileges of the current user, corresponding to a CVSS 3.1 score of 8.8.

Adobe security bulletin APSB10-02 and related vendor advisories from Secunia and OpenSUSE direct administrators to apply the vendor-supplied patches that update Reader and Acrobat to the fixed releases. Organizations should prioritize these updates on all Windows and Mac OS X installations to eliminate the affected code paths.
