An exploitable uninitialized pointer vulnerability exists in the rich text format parser of Atlantis Word Processor, version 3.2.7.2. A specially crafted document can cause certain RTF tokens to dereference a pointer that has been uninitialized and then write to it. An attacker must convince a victim to open a specially crafted document in order to trigger this vulnerability.

Weakness

The product accesses or uses a pointer that has not been initialized.

Affected Software

Name Vendor Start Version End Version
Atlantis_word_processor Atlantiswordprocessor 3.2.7.2 (including) 3.2.7.2 (including)

Extended Description

If the pointer contains an uninitialized value, then the value might not point to a valid memory location. This could cause the product to read from or write to unexpected memory locations, leading to a denial of service. If the uninitialized pointer is used as a function call, then arbitrary functions could be invoked. If an attacker can influence the portion of uninitialized memory that is contained in the pointer, this weakness could be leveraged to execute code or perform other attacks. Depending on memory layout, associated memory management behaviors, and product operation, the attacker might be able to influence the contents of the uninitialized pointer, thus gaining more fine-grained control of the memory location to be accessed.
