Description:
Some vulnerabilities have been reported in the Linux kernel. One has an unknown impact, the rest can be exploited by malicious, local users, or by malicious people, to cause a DoS (Denial of Service).
1) A boundary error exists in the ROSE "rose_rt_ioctl()" function due to missing verification of the ndigis argument of new routes. This can be exploited to crash the kernel by calling the function with a large ngidis argument.
2) Any user with permissions to access a SCSI tape device can send some commands, which may cause it to become unusable for other users.
3) A race condition in ebtables netfilter module (ebtables.c) when running on an SMP system operating under a heavy load, may be exploited to cause a DoS (kernel panic) via a series of packets.
4) An error in the maintaining of cache coherency in "mprotect.c" on Itanium IA64 processors can be exploited by local users to cause a DoS and possibly corrupt data by modifying PTE protections.
5) Certain debugging code that is present in the "choose_new_parent()" function in "kernel/exit.c" can be exploited by local users to cause a DoS.
Solution:
Vulnerabilities #1, #2 and #3 have been fixed in version 2.6.12-rc1.
Vulnerability #4 has been fixed in version 2.6.12-rc2.
Vulnerability #5 has been fixed in version 2.6.12-rc4.
