| Package | Affected versions | Patched versions |
|---|---|---|
| http server | ≥ 1.3.11, ≤ 1.3.20 |
mod_usertrack in Apache 1.3.11 through 1.3.20 generates session ID's using predictable information including host IP address, system time and server process ID, which allows local users to obtain session ID's and bypass authentication when these session ID's are used for authentication.
