Status Candidate

Overview

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.

Ubuntu Security Notice 2064-1 - Stephan Mueller reported an error in the Linux kernel's ansi cprng random number generator. This flaw makes it easier for a local attacker to break cryptographic protections. 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. Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's debugfs filesystem. An administrative local user could exploit this flaw to cause a denial of service (OOPS). Various other issues were also addressed.
