Summary

An Out-of-bounds Read issue was discovered in Adobe Flash Player before 28.0.0.137. This vulnerability occurs because of computation that reads data that is past the end of the target buffer. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    descriptionAn update for flash-plugin is now available for Red Hat Enterprise Linux 6 Supplementary. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update upgrades Flash Player to version 28.0.0.137. Security Fix(es) : * This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities, detailed in the Adobe Security Bulletins listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to disclose sensitive information or modify its settings when the victim loaded a page containing the malicious SWF content.
