Attackers can craft a malicious rules table entry with an oversized rule type value that is used without bounds checking as an index into an internal output-link table, resulting in an out-of-bounds write.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":49,"depthScoreParts":{"impact":48.4,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
