Overview
By embedding malicious code in a Portable Document Format (PDF) file, an attacker can cause arbitrary code to execute on the victim's system.
Description
The Adobe Acrobat PDF file format facility for specifying fonts contains buffer overflows in the /Registry and /Ordering entries. Each of these entries are not properly bounds checked, allowing at attacker to construct a malicious document which overflows an internal buffer and allows the execution of arbitary code. These entries are in the CIDSystemInfo dictionary. CID stands for "character identifier". The /Registry entry is for specifying which organization issued the character collection. For example "Adobe". The /Ordering entry is supposed to uniquely identify a character collection issued by the registry. An example could be "Japan1". More information about the PDF document format is available in the "Portable Document Format Reference Manual" from Adobe. |
Impact
An attacker could execute arbitrary code on systems running a vulnerable Adobe product when the user views a malicious PDF file. |
