TITLE:
Linux Kernel Information Disclosure and Security Bypass

SECUNIA ADVISORY ID:
SA34422

VERIFY ADVISORY:
http://secunia.com/advisories/34422/

DESCRIPTION:
Some security issues have been reported in the Linux Kernel, which
can be exploited by malicious, local users to disclose potentially
sensitive information and by malicious users to bypass certain
security restrictions.

1) A security issue is caused due to an error when storing eCryptfs
headers, which can be exploited to disclose certain kernel memory.

2) A security issue is caused due to nfsd not properly dropping the
"CAP_MKNOD" capability for unprivileged users, which can be exploited
to create device nodes.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits Florian Streibelt.
2) Igor Zhbanov
