CyberRota Analysis
AI-GeneratedVersions of Data::DisjointSet::Shared prior to 0.02 for Perl are vulnerable to critical out-of-bounds reads and writes due to an unvalidated parent index in the dsu_find function. This flaw allows a local attacker with write access to the backing file to manipulate the parent array, potentially leading to memory corruption or process crashes. Organizations utilizing this Perl module should prioritize patching to mitigate the risk of exploitation.
Original NVD Description
Data::DisjointSet::Shared versions before 0.02 for Perl allow out-of-bounds reads and writes via an unvalidated parent index in dsu_find. The attach-time validator dsu_validate_header checks the header scalars and region layout against the file size, but does not validate the array contents it then trusts. dsu_find walks and path-compresses parent[x] with x a raw file-stored index never bounded against the node count, so both the read and the compression write-back land out of bounds. A local peer that can write the backing file can leave the header valid while poisoning the parent array, so the next find or union both reads and writes through an out-of-bounds parent index, corrupting memory or crashing the process.
