Debian: DSA 284-1 Critical Flaw In Xfsdump Unsecured File Generation

The manner in which the quota information file is created is unsafe.. - -------------------------------------------------------------------------- Debian Security Advisory DSA 283-1 This email address is being protected from spambots. You need JavaScript enabled to view it. Debian -- Security Information Martin Schulze April 11th, 2003 Debian -- Debian security FAQ - -------------------------------------------------------------------------- Package : xfsdump Vulnerability : insecure file creation Problem-Type : local Debian-specific: no CVE Id : CAN-2003-0173 Ethan Benson discovered a problem in xfsdump, that contains administrative utilities for the XFS filesystem. When filesystem quotas are enabled xfsdump runs xfsdq to save the quota information into a file at the root of the filesystem being dumped. The manner in which this file is created is unsafe. While fixing this, a new option ``-f path' has been added to xfsdq(8) to specify an output file instead of using the standard output stream. This file is created by xfsdq and xfsdq will fail to run if it exists already. The file is also created with a more appropriate mode than whatever the umask happened to be when xfsdump(8) was run. For the stable distribution (woody) this problem has been fixed in version 2.0.1-2. The old stable distribution (potato) is not affected since it doesn't contain xfsdump packages. For the unstable distribution (sid) this problem has been fixed in version 2.2.8-1. We recommend that you upgrade your lpr package immediately. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
