kernel is vulnerable to privilege escalation. A buffer overflow flaw was found in the ecryptfs_uid_hash() function in the Linux kernel eCryptfs implementation. On systems that have the eCryptfs netlink transport (Red Hat Enterprise Linux 5 does) or where the β/dev/ecryptfsβ file has world writable permissions (which it does not, by default, on Red Hat Enterprise Linux 5), a local, unprivileged user could use this flaw to cause a denial of service or possibly escalate their privileges.
