Description:
Some vulnerabilities have been reported in the Linux kernel, which can be exploited by malicious, local users to bypass certain security restrictions or cause a DoS (Denial of service), and by malicious people to potentially cause a DoS.
1) An error exists in the implementation of the "sys_utimensat()" system call. This can be exploited to update the access or modification time of arbitrary files via specially crafted arguments passed to the affected system call.
2) A memory leak exists in the "ipip6_rcv()" function included in the IPv6 over IPv4 (SIP) tunneling driver. This can be exploited to potentially exhaust all available memory via specially crafted network packets.
3) An error when checking "mmap()" address limits on SPARC platforms can be exploited to crash the system.
The vulnerabilities are reported in version 2.6.25.2. Prior versions may also be affected.
