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 wasn't created with fixed permissions, which may lead to inproper permissions if the umask is too lax.
- 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.
