Detail
| A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) Ubuntu 5.10 (Breezy Badger) The following packages are affected: apache2-mpm-worker The problem can be corrected by upgrading the affected package to version 2.0.50-12ubuntu4.9 (for Ubuntu 4.10), 2.0.53-5ubuntu5.4 (for Ubuntu 5.04), or 2.0.54-5ubuntu3 (for Ubuntu 5.10). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: A memory leak was found in the Apache 2 'worker' module in the handling of aborted TCP connections. By repeatedly triggering this situation, a remote attacker could drain all available memory, which eventually led to a Denial of Service. |

| Id | Description |
|---|---|
| 20462 | Apache HTTP Server worker.c MPM Memory Exhaustion DoS Apache Multi-Processing Module (MPM) contains a flaw that may allow a remote denial of service. The issue is triggered when a malicious attacker uses aborted connection attempts to fill transaction pool memory, preventing the memory from being reused for other connections. This will result in loss of availability for the service. |
