CyberRota Analysis
AI-GeneratedVersions of Data::RadixTree::Shared prior to 0.02 for Perl are vulnerable to an out-of-bounds read due to insufficient validation of node and arena indices in the rdx_find_locked function. This flaw allows a local attacker with write access to the backing file to manipulate node records, potentially leading to memory corruption or process crashes. Organizations using affected versions should prioritize patching this vulnerability to mitigate the risk of exploitation.
Original NVD Description
Data::RadixTree::Shared versions before 0.02 for Perl allow an out-of-bounds read via unvalidated node and arena indices in rdx_find_locked. The attach-time validator rdx_validate_header checks the header scalars and region layout against the file size, but does not validate the node records it then trusts. rdx_find_locked indexes nodes[cur].children[k] and reads each node's label_off and label_len raw from the mmap'd segment, none bounded against the node count or the arena size. A local peer that can write the backing file can leave the header valid while poisoning the node records, so a lookup dereferences an out-of-bounds node or arena index, reading adjacent memory or crashing the process.
