Exposure of sensitive information, Privilege escalation

vulnerabilities, which can be exploited by malicious, local users to
disclose potentially sensitive information or gain escalated
privileges.

1) An integer overflow error within the "dccp_feat_change()" function
in net/dccp/feat.c can be exploited to cause a heap-based buffer
overflow.

2) An unspecified error in the 32-bit and 64-bit emulation can be
exploited to disclose potentially sensitive data via a specially
crafted binary.

3) An error while copying memory from userspace can be exploited to
disclose potentially sensitive information.
