A vulnerability in Adobe Acrobat and Reader could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.
The vulnerability is due to improper boundary checks performed by the affected software while handling certain PDF files. An unauthenticated, remote attacker could exploit the vulnerability by convincing a user to open a crafted PDF file. When processed, the file could cause a buffer overflow error that may corrupt memory. The attacker could use the memory corruption error to cause a DoS condition or execute arbitrary code on the system.
Adobe has confirmed the vulnerability and released updated software.
