Title: GNU Indent Local Heap Overflow Vulnerability
Severity: MODERATE
Description:
GNU Indent is an application used to improve the syntax of C, making it easier to read source code.
An overflow condition has been identified in the software that may allow an attacker to execute arbitrary code on a vulnerable system.
The issue has been reported to exist in the handle_token_colon() function of the software. The problem is reported to present itself when the application attempts to a parse a C source file (*.c). It has been reported that indent copies data from the file to a 1000 byte long buffer without sufficient boundary checking. A heap overflow condition may be triggered, potentially causing heap memory management structures to be corrupted. This can result in critical memory being overwritten and, ultimately, code execution with the privileges of the user running indent.
GNU Indent version 2.2.9 has been reported to be prone this issue, however, other versions may be affected as well.
