Mandrake Linux Security Advisory : sysklogd (MDKSA-2000:050-1)
High Nessus Plugin ID 61840
SynopsisThe remote Mandrake Linux host is missing a security update.
DescriptionA problem exists with the kernel logging daemon (klogd) in the sysklogd package. A 'format bug' makes klogd vulnerable to local root compromise, as well as the possibility for remote vulnerabilities under certain circumstances, which are unprobable. There is also a more probable semi-remote exploit via knfsd. This update provides a patched version of klogd that fixes these vulnerabilities.
A patch from Debian is now applied to the package as well which will prevent a kern.emerg log being walled to users due to a logic error in printchopped() that caused it to zero out the wrong portion of the buffer, which left a message of '<' with a priority of 0. This update also fixes a problem with klogd not working properly due to the previous update.
SolutionUpdate the affected sysklogd package.
