Description
This security bulletin contains information about 1 security vulnerability.
1) Integer underflow (CVE-ID: CVE-2005-0180)
The vulnerability allows a local user to read and manipulate data.
Multiple integer signedness errors in the sg_scsi_ioctl function in scsi_ioctl.c for Linux 2.6.x allow local users to read or modify kernel memory via negative integers in arguments to the scsi ioctl, which bypass a maximum length check before calling the copy_from_user and copy_to_user functions.
Remediation
Install update from vendor's website.
