Vulnerability Assessment Details
Check for the version of the kernel package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory MDKSA-2004:066 (kernel).
A number of vulnerabilities were discovered in the Linux kernel that are
corrected with this update:
Multiple vulnerabilities were found by the Sparse source checker that could
permit local users to elevate rights or gain access to kernel memory
Missing Discretionary Access Controls (DAC) checks in the chown(2) system call
could permit a possible hacker with a local account to change the group ownership of
arbitrary files, which could lead to root rights on affected systems
An information leak vulnerability that affects only ia64 systems was fixed
Insecure permissions on /proc/scsi/qla2300/HbaApiNode could permit a local user
to cause a DoS on the system
this only affects Mandrakelinux 9.2 and below
A vulnerability that could crash the kernel has also been fixed. This crash,
however, can only be exploited via root (in br_if.c).
The provided packages are patched to fix these vulnerabilities. All users are
encouraged to upgrade to these updated kernels.
To update your kernel, please follow the directions located at:
