Critical Bird3 Flaw Patched

Gnoppix Security has issued GSA-6379-1 to address a security vulnerability in the bird3 routing suite. The flaw could allow attackers to cause a denial of service.

What Happened

An issue in the resource management of bird3 permits remote exploitation. The bug exists in the Babel protocol handling, specifically a memory leak.

Who Is Affected

All users running bird3 on Gnoppix 23/25 and Gnoppix 25 systems must update immediately.

Mitigation Steps

Update your bird3 package to the patched version via the standard package manager. No other workarounds are available.

Background

The vulnerability was discovered during routine code auditing. The Babel protocol implementation failed to properly release allocated memory under specific network conditions. This leads to resource exhaustion over time. - Please update your systems.
