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
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
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
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
