Linux-Mandrake Security Update Advisory

Package name:           hylafax
Date:                   April 24th, 2001
Advisory ID:            MDKSA-2001:041

Affected versions:      7.1, 7.2, Corporate Server 1.0.1

Problem Description:

A problem exists with the HylaFAX program, hfaxd. When hfaxd tries to change it's queue directory and fails, it prints an error message via syslog by directly passing user supplied data as the format string. If hfaxd is installed setuid root, this behaviour can be exploited to gain root access locally. Note that Linux-Mandrake does not ship hfaxd setuid root by default.

Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command: rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS If you use MandrakeUpdate, the verification of md5 checksum and GPG signature is performed automatically for you.

To upgrade automatically, use MandrakeUpdate.

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

You can download the updates directly from one of the mirror sites 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 8.0, look for it in "updates/8.0/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.

Please be aware that sometimes it takes the mirrors a few hours to update.
