Title: Kitware GCC-XML 'find_flags' Script Insecure Temporary File Creation Vulnerability
Severity: LOW
Description:
GCC-XML is an application for generating an XML description of C++ code from GCC's internal representation.
The application creates temporary files in an insecure manner. Specifically, the issue affects the 'find_flags' script.
An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.
