Summary
Routinator, a software tool that validates Internet routing data (RPKI) by fetching updates via the RRDP protocol, is affected by this vulnerability. The flaw can cause it to accept incomplete update data, leading to missing information, or to run out of memory when processing an excessive number of delta entries.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
When Routinator encounters an RRDP notification file with gaps in the delta entries, it is still accepted and parsed, potentially leading to missing data. If it encounters too many delta entries it may run out of memory.
