Linux-Mandrake Security Update Advisory
________________________________________________________________________
Package name: cups
Date: February 5th, 2001
Original Advisory Date: February 1st, 2001
Advisory ID: MDKSA-2001:020-1
Affected versions: 7.2
________________________________________________________________________
Problem Description:
A problem exists in all versions of CUPS prior to 1.1.5 with the
httpGets() function. It could go into an infinite loop if a line
longer than the input buffer size was sent by a client. This could
be used as a DoS attack. As well, all occurances of sprintf() calls
were changed to snprintf(), and all occurances of strcpy() calls
were changed to strncpy() calls, both of which protect against
buffer overflows. Finally, CUPS now defaults to not broadcasting
the printer information anymore by default, and by default access is
only allowed from the local machine.
Update:
The previously released packages were improperly constructed using
the new library method currently used in the Linux-Mandrake Cooker,
and as such caused upgrade problems for existing 7.2 users. This
update corrects this and does not use the libcups1(-devel) packages
which caused the problem. Users who have already upgraded to the
updated cups packages announced last week will need to uninstall the
libcups1 packages and then upgrade cups again. To do this, at the
command line execute the following commands prior to running
MandrakeUpdate:
rpm -e libcups1-devel
rpm -e libcups1 --nodeps
Now you can update the cups packages properly via MandrakeUpdate.
________________________________________________________________________
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:
http://www.linux-mandrake.com/en/ftp.php3.
Updated packages are available in the "updates/[ver]/RPMS/"
directory. For example, if you are looking for an updated RPM
package for Linux-Mandrake 7.2, look for it in "updates/7.2/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.
