Package : storebackup
Vulnerability : several
Problem-Type : local
Debian-specific: no
CVE ID : CVE-2005-3146 CVE-2005-3147 CVE-2005-3148
Debian Bug : 332434

Several vulnerabilities have been discovered in the backup utility
storebackup. The Common Vulnerabilities and Exposures project identifies
the following problems:

CVE-2005-3146

Storebackup creates a temporary file predictably, which can be
exploited to overwrite arbitrary files on the system with a symlink
attack.

CVE-2005-3147

The backup root directory is created with world-readable permissions,
which may leak sensitive data.

CVE-2005-3148

The user and group rights of symlinks are set incorrectly when making
or restoring a backup, which may leak sensitive data.

The old stable distribution (woody) doesn't contain storebackup packages.

For the stable distribution (sarge) these problems have been fixed in
version 1.18.4-2sarge1.

For the unstable distribution (sid) these problems have been fixed in
version 1.19-2.

We recommend that you upgrade your storebackup package.
