CVE-2011-0463

Priority
Description
The ocfs2_prepare_page_for_write function in fs/ocfs2/aops.c in the Oracle
Cluster File System 2 (OCFS2) subsystem in the Linux kernel before
2.6.39-rc1 does not properly handle holes that cross page boundaries, which
allows local users to obtain potentially sensitive information from
uninitialized disk locations by reading a file.
Ubuntu-Description
Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly
clear memory when writing certain file holes. A local attacker could
exploit this to read uninitialized data from the disk, leading to a loss of
privacy.
