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
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.
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
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
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 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.
Please be aware that sometimes it takes the mirrors a few hours
to update, so if you want an immediate upgrade, please use one of
the two above-listed mirrors.
