TITLE:
Linux Kernel Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA30241

VERIFY ADVISORY:
http://secunia.com/advisories/30241/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, DoS

WHERE:
>From remote

OPERATING SYSTEM:
Linux Kernel 2.6.x
http://secunia.com/product/2719/

DESCRIPTION:
Some vulnerabilities have been reported in the Linux kernel, which
can be exploited by malicious, local users to bypass certain security
restrictions and by malicious people to potentially cause a DoS
(Denial of Service).

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.

The vulnerabilities are reported in version 2.6.25.2. Prior versions
may also be affected.

SOLUTION:
Update to version 2.6.25.3.

PROVIDED AND/OR DISCOVERED BY:
1) Reported by the vendor.
2) Paul Marks.
