Linux kernel Omnikey CardMan 4040 drivers buffer overflow

kernel-cardman4040drivers-bo (32880) The risk level is classified as HighHigh Risk

Description:

Linux kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the cm4040_read() and cm4040_write() drivers. By sending a large amount of data, a local attacker could overflow a buffer and execute arbitrary code on the system with root privileges or cause the server to crash.

For Red Hat Linux (kernel):
Refer to RHSA-2007:0099 for patch, upgrade, or suggested workaround information. See References.

For Mandriva Linux (kernel):
Refer to MDKSA-2007:078 for patch, upgrade, or suggested workaround information. See References.

For Debian Linux (kernel):
Refer to DSA-1286-1 for patch, upgrade, or suggested workaround information. See References.

For Ubuntu Linux (linux-source):
Refer to USN-489-1 for patch, upgrade, or suggested workaround information. See References.

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