A vulnerability in Adobe Acrobat and Reader could allow an unauthenticated, remote attacker to execute arbitrary code or cause a denial of service (DoS) condition on a targeted system.
The vulnerability is due to a memory corruption error within the affected software while processing certain user-supplied input. An attacker could exploit this vulnerability by convincing a user to open a crafted file or convince a user to visit a web page designed to submit crafted input to the affected software. Processing the crafted input could allow the attacker to execute arbitrary code or cause a DoS condition on a targeted system.
Adobe has confirmed the vulnerability and released software updates.
