Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the log enrichment process when handling writev system calls. An attacker can cause memory corruption or leak adjacent memory by crafting a multi-segment writev call where the total byte count exceeds the length of the first segment, leading to overreading and overwriting of user buffers.
