A flaw in the sysfs_readdir function allowed a local user to cause a
denial of service by dereferencing a NULL pointer. (CVE-2007-3104)
A buffer overflow was discovered in the random number generator. In
environments with granular assignment of root privileges, a local
attacker could gain additional privileges. (CVE-2007-3105)
A flaw was discovered in the usblcd driver. A local attacker could
cause large amounts of kernel memory consumption, leading to a denial
of service. (CVE-2007-3513)

reset process death signal handlers. A local user could manipulate
this to send signals to processes they would not normally have access
