                Linux-Mandrake Security Update Advisory

Package name:           sysklogd
Date:                   September 18th, 2000
Advisory ID:            MDKSA-2000:050

Affected versions:      6.0, 6.1, 7.0, 7.1

Problem Description:

A 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.

Please verify these md5 checksums of the updates prior to upgrading to ensure the integrity of the downloaded package. You can do this by running the md5sum program on the downloaded package by using "md5sum package.rpm".

If you want to upgrade manually, download the updated package from one of our FTP server mirrors and uprade with "rpm -Uvh package_name".

You can download the updates directly from:

Or try one of the other mirrors listed at:


Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Linux-Mandrake 7.1, look for it in "updates/7.1/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.
