Description

Multiple stack-based buffer overflows in net/netfilter/ipvs/ip_vs_ctl.c in the Linux kernel before 2.6.33, when CONFIG_IP_VS is used, allow local users to gain privileges by leveraging the CAP_NET_ADMIN capability for (1) a getsockopt system call, related to the do_ip_vs_get_ctl function, or (2) a setsockopt system call, related to the do_ip_vs_set_ctl function. A user/program with CAP_NET_ADMIN privileges could use this flaw to further escalate their privileges on a system.

From the Ubuntu Security Team

A flaw was discovered in the Linux kernel's IP Virtual Server (IP_VS) support. A local user with the CAP_NET_ADMIN capability could exploit this flaw to gain additional administrative privileges.
