1) Missing release of memory after effective lifetime (CVE-ID: CVE-2005-3807)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
Memory leak in the VFS file lease handling in locks.c in Linux kernels 2.6.10 to 2.6.15 allows local users to cause a denial of service (memory exhaustion) via certain Samba activities that cause an fasync entry to be re-allocated by the fcntl_setlease function after the fasync queue has already been cleaned by the locks_delete_lock function.
Remediation
Install update from vendor's website.
