Title: Lucent RADIUS Format String Vulnerability
Severity: CRITICAL
Description:
The Lucent RADIUS implementation is a user authentication software package designed to offer enhanced security services to users needing remote access to various resources. The package is no longer maintained by Lucent, and is public domain.
A problem with the software package makes it possible for remote users to execute arbitrary code. In the event that this vulnerability is exploited, a remote user can gain superuser access to the system.
Format string vulnerabilities exist within the log.c, users.c, and version.c. These programs make use of function calls in which certain format specifiers can be used to write to supplied locations in memory. Bugs in the implementation of these functions may allow users to write to process memory.
Attackers can use these format specifiers to overwrite critical values in memory with malicious replacements that will cause the execution of supplied shellcode or otherwise compromise enhanced privileges.
Affected Products:
- Simon Horms RADIUS 2.1.0 -2
