CVE-2024-31193Network attack vector

Service interruption via group-reply parser over-read

Published Sep 18, 2024 · Updated Sep 18, 2024

Out-of-bounds read in ONF libfluid 0.1.0 allows remote attackers to interrupt services through a crafted OpenFlow group reply. MultipartReplyGroup::unpack parses OpenFlow 1.3 group-reply data, but the published advisory does not identify the missing bounds check or exact over-read operation. Unauthenticated network access to a component that invokes this parser is required, and the reported consequence is a denial-of-service condition.
