|Bugzilla:||624327: CVE-2010-3015 kernel: integer overflow in ext4_ext_get_blocks()|
The MITRE CVE dictionary describes this issue as:
Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation.
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.
