Summary

A double free vulnerability exists in librz/bin/format/le/le.c in the function le_load_fixup_record(). When processing malformed or circular LE fixup chains, relocation entries may be freed multiple times during error handling. A specially crafted LE binary can trigger heap corruption and cause the application to crash, resulting in a denial-of-service condition. An attacker with a crafted binary could cause a denial of service when the tool is integrated on a service pipeline.
