Description:
Some security issues have been reported in the Linux Kernel, which can be exploited by malicious, local users to bypass certain security restrictions, to gain escalated privileges, or to cause a DoS (Denial of Service).
1) The USBLCD driver does not limit the memory consumption during writes to the device. This can be exploited to cause an out-of-memory condition by writing a large amount of data to an affected device.
Successful exploitation requires write access to a device using the driver.
2) An error in the implementation of the "sys_setrlimit()" system call can be exploited to bypass CPU time limits by setting RLIMIT_CPU to 0.
3) An error in the "ftruncate()" functionality can be exploited to potentially gain escalated group privileges by creating a file in a setgid directory.
