CVE-2014-1690

Status Candidate

Overview

The help function in net/netfilter/nf_nat_irc.c in the Linux kernel before 3.12.8 allows remote attackers to obtain sensitive information from kernel memory by establishing an IRC DCC session in which incorrect packet data is transmitted during use of the NAT mangle feature.

Red Hat Security Advisory 2014-0439-01
Posted Apr 28, 2014
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2014-0439-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement packets. An attacker able to send a large number of RA packets to a target system could potentially use this flaw to crash the target system. A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system.

Ubuntu Security Notice 2158-1 - 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. Nico Golde and Fabian Yamaguchi reported buffer underflow errors in the implementation of the XFS filesystem in the Linux kernel. A local user with CAP_SYS_ADMIN could exploit these flaw to cause a denial of service (memory corruption) or possibly other unspecified issues. Various other issues were also addressed.

Ubuntu Security Notice USN-2137-1
Posted Mar 7, 2014
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2137-1 - An information leak was discovered in the Linux kernel when built with the NetFilter Connection Tracking (NF_CONNTRACK) support for IRC protocol (NF_NAT_IRC). A remote attacker could exploit this flaw to obtain potentially sensitive kernel information when communicating over a client- to-client IRC connection(/dcc) via a NAT-ed network. Matthew Thode reported a denial of service vulnerability in the Linux kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN capability (and the SELinux mac_admin permission if running in enforcing mode) could exploit this flaw to cause a denial of service (kernel crash). Various other issues were also addressed.
