CVE-2011-1834: utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly maintain the mtab file during...

Security readout for executives and security teams

This flaw affects ecryptfs-utils before version 90. A local user could trigger mount table corruption or get around intended unmount restrictions. It is not a remote internet-facing issue based on the supplied sources, but it can disrupt systems where local shell users or shared accounts exist. Systems are likely exposed only if ecryptfs-utils earlier than 90 is installed and local users can interact with eCryptfs private mounts. Vendor advisories exist for Linux distribution packaging, but the supplied bundle does not enumerate specific fixed distro package versions. Treat as a targeted maintenance item for Linux systems with local users. It is not evidenced as internet-exploited, but shared servers, lab hosts, and legacy desktops using eCryptfs should be checked and updated. Mitigation focus: Upgrade ecryptfs-utils to version 90 or a vendor-fixed package.; Review Ubuntu and SUSE advisories for distribution-specific fixed builds.; Check Red Hat tracking for applicability to managed Linux fleets..
