Adobe Flash Player versions 10.0.45.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability is due to improper processing of parameters by the LocalConnection function. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to view a malicious website. If successful, the attacker could exploit this vulnerability to execute arbitrary code with the privileges of the user.
Adobe has confirmed this vulnerability and released updated software.
Indicators of Compromise
Adobe Flash Player versions 10.0.45.2 and prior are vulnerable.
The vulnerability is due to improper processing of parameters by the LocalConnection function in the Flash player. Malformed strings processed by the function could trigger memory corruption.
An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to view a malicious website that contains embedded Flash content or convincing a user to view a Flash movie file. When opened, the Flash content could trigger memory corruption that the attacker could use to execute arbitrary code with the privileges of the user.
To exploit the vulnerability, an attacker must convince a user to view a malicious website. The attacker may provide links to users within e-mail messages or by posting URLs on public websites. An attacker may also attempt to embed malicious content within other websites, potentially in advertisements from third-party services on sites with mixed content.
Administrators are advised to apply the appropriate updates.
Users should verify that unsolicited links are safe to follow.
Administrators are advised to implement an intrusion prevention system (IPS) or intrusion detection system (IDS) to help detect and prevent attacks that attempt to exploit this vulnerability.
Administrators are advised to monitor affected systems.
