CVE-2014-0069: Buffer Overflow

First published: Wed Feb 12 2014(Updated: )

A flaw was found in the way cifs handled iovecs with bogus pointers userland passed down via writev() during uncached writes. An unprivileged local user with access to cifs share could use this flaw to crash the system or leak kernel memory. Privilege escalation cannot be ruled out (since memory corruption is involved), but is unlikely. The default cache settings for cifs mounts on Red Hat Enterprise Linux prohibit successful exploitation of this issue. Acknowledgements: Red Hat would like to thank Al Viro for reporting this issue.
