|Bugzilla:||601006: CVE-2010-2066 kernel: ext4: Make sure the MOVE_EXT ioctl can't overwrite append-only files|
The MITRE CVE dictionary describes this issue as:
The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel before 2.6.35 allows local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor.
This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include support for the Ext4 filesystem. A future kernel update in Red Hat Enterprise Linux 5 will address this issue.
