A vulnerability in Adobe Acrobat and Reader could allow an unauthenticated, remote attacker to cause a heap-based buffer overflow condition.
The vulnerability occurs because the affected software performs improper bounds checks on user input. An unauthenticated, remote attacker could exploit this vulnerability by convincing a targeted user to open a malicious PDF document designed to submit crafted data to the affected software. A successful exploit could allow the attacker to trigger a heap-based buffer overflow condition that the attacker could use to execute arbitrary code.
Adobe confirmed the vulnerability and released updated software.
