USN-793-1 -- Linux kernel vulnerabilities

ID: oval:org.secpod.oval:def:700305Date: (C)2011-05-13   (M)2017-10-04
Class: PATCHFamily: unix




Igor Zhbanov discovered that NFS clients were able to create device nodes even when root_squash was enabled. An authenticated remote attacker could create device nodes with open permissions, leading to a loss of privacy or escalation of privileges. Only Ubuntu 8.10 and 9.04 were affected. Dan Carpenter discovered that SELinux did not correctly handle certain network checks when running with compat_net=1. A local attacker could exploit this to bypass network checks. Default Ubuntu installations do not enable SELinux, and only Ubuntu 8.10 and 9.04 were affected. Shaohua Li discovered that memory was not correctly initialized in the AGP subsystem. A local attacker could potentially read kernel memory, leading to a loss of privacy. Benjamin Gilbert discovered that the VMX implementation of KVM did not correctly handle certain registers. An attacker in a guest VM could exploit this to cause a host system crash, leading to a denial of service. This only affected 32bit hosts. Ubuntu 6.06 was not affected. Thomas Pollet discovered that the Amateur Radio X.25 Packet Layer Protocol did not correctly validate certain fields. A remote attacker could exploit this to read kernel memory, leading to a loss of privacy. Trond Myklebust discovered that NFS did not correctly handle certain long filenames. An authenticated remote attacker could exploit this to cause a system crash, leading to a denial of service. Only Ubuntu 6.06 was affected. Oleg Nesterov discovered that the kernel did not correctly handle CAP_KILL. A local user could exploit this to send signals to arbitrary processes, leading to a denial of service. Daniel Hokka Zakrisson discovered that signal handling was not correctly limited to process namespaces. A local user could bypass namespace restrictions, possibly leading to a denial of service. Only Ubuntu 8.04 was affected. Pavel Emelyanov discovered that network namespace support for IPv6 was not correctly handled. A remote attacker could send specially crafted IPv6 traffic that would cause a system crash, leading to a denial of service. Only Ubuntu 8.10 and 9.04 were affected. Neil Horman discovered that the e1000 network driver did not correctly validate certain fields. A remote attacker could send a specially crafted packet that would cause a system crash, leading to a denial of service. Pavan Naregundi discovered that CIFS did not correctly check lengths when handling certain mount requests. A remote attacker could send specially crafted traffic to cause a system crash, leading to a denial of service. Simon Vallet and Frank Filz discovered that execute permissions were not correctly handled by NFSv4. A local user could bypass permissions and run restricted programs, possibly leading to an escalation of privileges. Jeff Layton and Suresh Jayaraman discovered buffer overflows in the CIFS client code. A malicious remote server could exploit this to cause a system crash or execute arbitrary code as root. Mikulas Patocka discovered that /proc/iomem was not correctly initialized on Sparc. A local attacker could use this file to crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. Miklos Szeredi discovered that OCFS2 did not correctly handle certain splice operations. A local attacker could exploit this to cause a system hang, leading to a denial of service. Ubuntu 6.06 was not affected
