AI-analyzed exploit summary This exploit demonstrates a remote denial-of-service vulnerability in the Linux kernel by triggering an out-of-memory error. It uses a script named 'feedftp' to exhaust system resources, affecting Linux kernel versions 2.6.35 and earlier.
Description
net/core/net_namespace.c in the Linux kernel 2.6.32 and earlier does not properly handle a high rate of creation and cleanup of network namespaces, which makes it easier for remote attackers to cause a denial of service (memory consumption) via requests to a daemon that requires a separate namespace per connection, as demonstrated by vsftpd.
