Fortinet Discovers Adobe Acrobat Reader CoolType Heap Overflow Vulnerability
Fortinet's FortiGuard Labs has discovered a heap overflow vulnerability in Adobe Acrobat and Reader.
Adobe Acrobat and Reader are products of Adobe Systems. They are developed to view, create, manipulate, print and manage files in Portable Document Format (PDF). They are the most popular PDF applications. The freeware Adobe Reader, available for several desktop and mobile platforms, can view, print and annotate PDF files. The commercial proprietary Acrobat, available for Microsoft Windows and OS X only, can also create, edit, convert, digitally sign, encrypt, export and publish PDF files.
A heap overflow vulnerability has been discovered in Acrobat and Reader. The vulnerability is caused by a crafted PDF file which causes an out of bounds memory access, due to improper bounds checking when manipulating an array pointer. It could allow malicious users to create code execution scenarios.
Users should apply the solution provided by Adobe.
