wb2osz/direwolf <= 1.8.1 Reachable Assertion DoS

Impact

Dire Wolf versions up to 1.8.1 contain a reachable assertion vulnerability in the APRS MIC-E decoder, allowing a remote attacker to cause a denial of service with a specially crafted AX.25 frame. The vulnerability is triggered by an empty or truncated comment field in a MIC-E message. This causes the application to terminate immediately.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

wb2osz/direwolf (Dire Wolf) versions up to and including 1.8.1, prior to commit 3658a87, contain a reachable assertion vulnerability in the APRS MIC-E decoder function aprs_mic_e() located in src/decode_aprs.c. When processing a specially crafted AX.25 frame containing a MIC-E message with an empty or truncated comment field, the application triggers an unhandled assertion checking for a non-empty comment. This assertion failure causes immediate process termination, allowing a remote, unauthenticated attacker to cause a denial of service by sending malformed APRS traffic.
