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. (CVE-2009-1072)

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. (CVE-2009-1184)

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. (CVE-2009-1192)

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. (CVE-2009-1242)

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. (CVE-2009-1265)

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. (CVE-2009-1336)

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. (CVE-2009-1337)

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. (CVE-2009-1338)

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. (CVE-2009-1360)

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. (CVE-2009-1385)

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. (CVE-2009-1439)

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 ... [Please see the references for more information on the vulnerabilities]");
