Duplicate Advisory: uutils coreutils Uses Incorrectly-Resolved Name or Reference
### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-8vrf-r662-2w2v. This link is maintained to preserve external references. ### Original Description The cp utility in uutils coreutils, when performing recursive copies (-R), incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are destroyed (e.g., /dev/null becomes a regular file). This behavior can lead to runtime denial of service through disk exhaustion or process hangs when reading from unbounded device nodes.
AI Analysis
Technical Summary
In uutils coreutils' cp utility before version 0.7.0, recursive copy operations (-R) mishandle character and block device nodes by treating them as stream sources rather than preserving them as device nodes. The implementation reads bytes into regular files instead of using mknod, which results in loss of device semantics (e.g., /dev/null becomes a regular file). This flaw can lead to denial of service conditions such as disk exhaustion or process hangs when interacting with device nodes that produce unbounded data streams. The advisory is marked as a duplicate and withdrawn, referencing GHSA-8vrf-r662-2w2v for further details.
Potential Impact
The vulnerability does not affect confidentiality but impacts integrity and availability. Specifically, it can cause denial of service by exhausting disk space or causing processes to hang when reading from device nodes that are incorrectly copied as regular files. This can disrupt system operations relying on device nodes.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory GHSA-8vrf-r662-2w2v for current remediation guidance. Since this advisory is a duplicate and withdrawn, refer to the original advisory for official fixes or mitigations.
