Debian Security Advisory DSA 283-1 [email protected] Martin Schulze
April 11th, 2003
- --------------------------------------------------------------------------

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.
