Background
Cscope is a tool used for browsing source code in various programming languages. It allows users to search for symbols, functions, and definitions within a codebase. This vulnerability affects versions of Cscope before 15.7a. The vulnerability arises from multiple buffer overflows, which can be triggered by providing long strings as input, such as source-code tokens or pathnames. These buffer overflows are caused by integer overflows in certain cases. It is important to note that this vulnerability is a result of an incomplete fix for CVE-2004-2541.
Vulnerability Detail
The buffer overflows in Cscope before 15.7a can be exploited by remote attackers to execute arbitrary code. By sending specially crafted input, an attacker can overflow buffers and overwrite critical data structures, leading to the execution of arbitrary code. This can result in a complete compromise of the affected system. The vulnerability is caused by integer overflows in certain cases, allowing the attacker to bypass input length restrictions. It is crucial to address this vulnerability to prevent potential remote code execution attacks.
