Mandrake Linux Security Advisory : kernel (MDKSA-2004:066)
High Nessus Plugin ID 14165
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionA 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 allow local users to elevate privileges or gain access to kernel memory (CVE-2004-0495).
Missing Discretionary Access Controls (DAC) checks in the chown(2) system call could allow an attacker with a local account to change the group ownership of arbitrary files, which could lead to root privileges on affected systems (CVE-2004-0497).
An information leak vulnerability that affects only ia64 systems was fixed (CVE-2004-0565).
Insecure permissions on /proc/scsi/qla2300/HbaApiNode could allow a local user to cause a DoS on the system; this only affects Mandrakelinux 9.2 and below (CVE-2004-0587).
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.
