Linux kernel vc_resize denial of service

linux-vcresize-dos (18523) The risk level is classified as MediumMedium Risk

Description:

Linux kernel is vulnerable to an integer overflows in the vc_resize function in the vt.c file. A local attacker could exploit this vulnerability to cause the kernel to crash.


Consequences:

Denial of Service

Remedy:

For Linux kernel 2.6.x:
Upgrade to the latest version of Linux kernel (2.6.10rc3bk5 or later), available from the Linux kernel Web site. See References.

For Ubuntu Linux:
Upgrade to the latest linux-image package (2.6.8.1-16.5 or later), as listed in USN-47-1 December 23, 2004 for more information. See References.

For SUSE Linux:
Upgrade to the latest kernel, as listed below. Refer to SUSE Security Announcement SUSE-SA:2005:018 for more information. See References.

x86:
SUSE Linux 9.2: 2.6.8-24.13 or later
SUSE Linux 9.1: 2.6.5-7.151 or later
SUSE Linux 9.0: 2.4.21-280 or later
SUSE Linux 8.2: 2.4.20.SUSE-131 or later

x86-64 Platform:
SUSE Linux 9.2: 2.6.8-24.13 or later
SUSE Linux 9.1: 2.6.5-7.151 or later
SUSE Linux 9.0: 2.4.21-280 or later

For Debian GNU/Linux:
Refer to DSA-1070-1, DSA-1069-1, DSA-1067-1, or DSA-1082-1 for patch, upgrade, or suggested workaround information. See References.

For other distributions:
Contact your vendor for upgrade or patch information.
