Description
This security bulletin contains information about 1 security vulnerability.
1) Resource exhaustion (CVE-ID: CVE-2005-3660)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
Linux kernel 2.4 and 2.6 allows attackers to cause a denial of service (memory exhaustion and panic) by creating a large number of connected file descriptors or socketpairs and setting a large data transfer buffer, then preventing Linux from being able to finish the transfer by causing the process to become a zombie, or closing the file descriptor without closing an associated reference.
Remediation
Install update from vendor's website.
