Linux kernel Vicam USB driver denial of service
| linux-vicam-dos (15246) |  Medium Risk |
Description:
Linux kernel is vulnerable to a denial of service. The copy_from_user() function is not used to access userspace, which crosses security boundaries. A local attacker could exploit this vulnerability to possibly cause a denial of service.
Consequences:
Denial of Service
Remedy:
For Linux Kernel 2.4.x:
Upgrade to the latest version of Linux kernel (2.4.25 or later), available from the Linux Kernel Web site. See References.
For Red Hat Linux 9:
Upgrade to the latest kernel package (2.4.20-30.9 or later), as listed in RHSA-2004:065-04. See References.
For Red Hat Linux:
Refer to RHSA-2005:293-16 for patch, upgrade, or suggested workaround information. See References.
For SuSE Linux:
Upgrade to the latest kernel package, as listed below. Refer to SuSE Security Announcement SuSE-SA:2004:005 for more information. See References.
SuSE Linux 9.0 (Intel): 2.4.21-192 or later
SuSE Linux 8.2: 2.4.20-105 or later
SuSE Linux 8.1: 2.4.21-189 or later
SuSE Linux 9.0 (x86_64 Platform): 2.4.21-201 or later
For Mandrake Linux:
Upgrade to the latest kernel package, as listed below. Refer to MandrakeSoft Security Advisory MDKSA-2004:015 : kernel for more information. See References.
Mandrake Linux 9.0, Multi Network Firewall 8.2, and Corporate Server 2.1: 2.4.19.38mdk-1-1mdk or later

Mandrake Linux 9.2: 2.4.22.28mdk-1-1mdk or later
For Mandrake Linux:
Upgrade to the latest kernel package, as listed below. Refer to MandrakeSoft Security Advisory MDKSA-2004:015-1 : kernel for more information. See References.
Mandrake Linux Corporate Server 2.1: 2.4.19.38mdk-1-1mdk or later
For Conectiva Linux:
Upgrade to the latest kernel package, as listed below. Refer to Conectiva Linux Security Announcement CLSA-2004:846 for more information. See References.
Conectiva Linux 8: 2.4.19-1U80_24cl or later
Conectiva Linux 9: 2.4.21-31301U90_18cl or later
For Ubuntu Linux:
Upgrade to the latest linux-image package (2.6.8.1_2.6.8.1-16.10 or later), as listed in USN-60-0 January 14, 2005 for more information. See References.
