Debian Security Advisory DSA 1022-1 security@debian.org

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.
