{"id":"DEBIAN-CVE-2025-34458","details":"wb2osz/direwolf (Dire Wolf) versions up to and including 1.8, 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.","modified":"2026-09-01T20:05:46.695381505Z","published":"2025-12-22T22:16:04.687Z","upstream":["CVE-2025-34458"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-34458"}],"affected":[{"package":{"name":"direwolf","ecosystem":"Debian:14","purl":"pkg:deb/debian/direwolf?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.1+dfsg-2"}]}],"versions":["1.7+dfsg-2","1.8.1+dfsg-1","1.8.1+dfsg-2~bpo13+1","1.8~beta1+dfsg-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-34458.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
