OpenTelemetry eBPF Instrumentation: Memcached payload length overflow can crash OBI

Summary A remotely reachable integer overflow in OBI's memcached text protocol parser can crash the OBI process and cause denial of service. When parsing memcached storage commands such as set, add, replace, append, prepend, or cas, OBI accepts extremely large values and adds the payload delimite...

GHSA-J8P6-96VP-F3R9 OpenTelemetry eBPF Instrumentation: MongoDB parser panics on malformed wire messages

Summary Malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated...

GHSA-VVMG-8MJR-G6Q3 OpenTelemetry eBPF Instrumentation: Log enricher writev path can overread and overwrite user buffers

Summary OBI's log enricher mishandles writev buffers by reading only the first iovec entry but using the total ioviter.count as the copy length. When log injection is enabled, a crafted multi-segment writev call can make OBI read and overwrite memory beyond the first segment. Details In...

OpenTelemetry eBPF Instrumentation: Unbounded BPF internal metrics replay can exhaust CPU

Summary OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the metrics exporter to spend excessive CPU time in a tight loop every collection interval. Details The vulnerable loop is in...
