When parsing compressed labels in mDNS messages, the rr_decode function's return value is not checked, leading to a double free that could be exploited to execute arbitrary code. An attacker can send an mDNS message to trigger this vulnerability.\n\n## Affected\n\n- `libmicrodns = 0.1.0`\n- `debian_linux = 9.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":53.9,"likelihood":0.8,"exploitation":0,"ransomware":0},"changes":[]}
