Discussion

University of Minnesota Gopher Multiple Remote Vulnerabilities

Multiple remote vulnerabilities affect Gopher. These issues are due to a failure of the application to properly sanitize user-supplied data and a failure to verify input sizes.

The first issue is an integer overflow, the second issue is a format string vulnerability.

An attacker may leverage these issues to crash the affected daemon. These issues may also be leveraged to execute arbitrary code with the privileges of the gopherd process. This may facilitate unauthorized access.
