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.
