Xerox has released a security bulletin and updated software to address the Adobe Flash Player flash content processing cross-site scripting vulnerability.
Description
Adobe Flash Player contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks.
The vulnerability is due to insufficient user-input sanitization performed by the affected software. An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to visit a malicious web page and follow a crafted link. When processed, the web page could allow an attacker to execute arbitrary script code in the security context of the affected site or the affected webmail service.
Adobe has confirmed the vulnerability and released software updates.
