CVE-2010-2537 kernel: btrfs: check for append only file in the clone ioctl
Last modified: 2010-08-01 23:57:52 EDT
Description of problem:
The existing [btrfs] code would have allowed you to overwrite append-only files. Not an expected behaviour.
The kernel in Red Hat Enterprise Linux 6 has support for Btrfs by default.
Not vulnerable. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, 5 and Red Hat Enterprise MRG as they did not include support for Btrfs, a new copy on write filesystem.
Red Hat would like to thank Dan Rosenberg for responsibly reporting this issue.
