ncpfs 2.2.6 and earlier attempts to use (1) ncpmount to append to the /etc/mtab file and (2) ncpumount to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089.

Security readout for executives and security teams

This is a legacy local-user issue in ncpfs mount helpers. A user already on the system may be able to corrupt /etc/mtab, which records mounted filesystems. The business risk is mainly disruption or confusing system administration on older systems, not remote compromise. Exposure is most likely on legacy Unix/Linux systems that still have ncpfs 2.2.6 or earlier installed and allow local users to run the relevant mount helpers. Modern systems without ncpfs, without these helpers, or without local untrusted users are unlikely to be affected. Treat as low priority unless legacy ncpfs systems remain in production with many local users. Fold remediation into legacy Linux hygiene, package cleanup, and decommissioning work rather than emergency response. Mitigation focus: Inventory systems for ncpfs packages at version 2.2.6 or earlier.; Check vendor advisories or distribution packages for fixed ncpfs updates.; Remove ncpfs where NetWare/NCP filesystem support is no longer needed..
